GDB 7.11 does not build if compiled against uclibc-ng (1.0.12 was used,
but the problematic code exists in 1.0.13 as well). The reason is that
GDB release includes its own obstack implementation, but elides the code
if <gnu-versions.h> declares a compatible obstack implementation in
libc. uclibc-ng does claim compatible obstack interface (GDB expects
version 2, but accepts version 1 if sizeof(int) == sizeof(size_t)),
however, uclibc-ng does not provide the _obstack_free symbol that is a
part of the interface (glibc does provide this symbol). This later
causes a link failure.
The attached patch makes uclibc-ng enables an alias _obstack_free ->
obstack_free.

On systems where uClibc doesn't provide an arch specific byteswap.h,
we fall back on bits/byteswap-common.h. However, there is a bug
in this header in the __bswap_constant_64(x) macro. If, for example,
a double is passed, we get 'invalid operands to binary &' in which we
mismatch a 'double' and 'long long unsigned int'. The newer glibc
headers fix this and so we import them. Also, since the inclusion of
byteswap.h is not appropriate for assembly code, we guard a portion
of endian.h which uses byteswap.h from inclusion in any assembly.
This is needed, for example, for f2fs-tools 1.6.0 on 32-bit big
endian PowerPC.

Currently, the Thumb support on ARM has three related Config.in
options, which are not trivial for users to understand, and are in
fact not needed:
- The USE_BX option is not needed: knowing whether BX is available or
not is easy. If you have an ARM > v4 or ARMv4T, then BX is
available, otherwise it's not. This is the logic used in glibc.
- The USE_LDREXSTREX option is not needed: whenever Thumb2 is
available, ldrex/strex are available, so we can simply rely on
__thumb2__ to determine whether ldrex/strex should be used, without
requiring a Config.in option.
- Once USE_BX and USE_LDREXSTREX are removed, the only thing left
that COMPILE_IN_THUMB does is to set -mthumb. This makes the option
unnecessary, as on ARM at least, the user is already supposed to
pass -march=<foo> or other compiler options tuning the library for
a specific ARM variant. There is no reason to do otherwise for
Thumb, which allows to get rid of the COMPILE_IN_THUMB option.

Register window saving loop in __sigsetjmp incorrectly calculates offset
in the jmp_buf in case it was called with call12. The bug was introduced

As recently reported on the Buildroot list:
http://lists.busybox.net/pipermail/buildroot/2016-March/155325.html
DNS lookups with Node.js currently fails on uClibc-ng. The reason for this
is the way AI_V4MAPPED is handled. According to POSIX, AI_V4MAPPED should
be ignored unless ai_family is AF_INET6:
http://pubs.opengroup.org/onlinepubs/9699919799/functions/freeaddrinfo.html
If the AI_V4MAPPED flag is specified along with an ai_family of AF_INET6,
then getaddrinfo() shall return IPv4-mapped IPv6 addresses on finding no
matching IPv6 addresses (ai_addrlen shall be 16). The AI_V4MAPPED flag
shall be ignored unless ai_family equals AF_INET6.
uClibc-ng was also handling AI_V4MAPPED for AF_UNSPEC, fix that.

Currently a miss on a search-path entry is counted as a retry. This means that
users with more than (num_nameservers * retries) entries in their search path
list fail before trying all search paths. Concretely, a single nameserver with
4 search paths will never try the 4th search because the default retry is 3.
The code doesn't currently retry a given nameserver in case of an error, so
retries is sort of meaningless (though there are some comments indicating it
might come). This change only treats total failure of a nameserver (try next
server) as a retry.

__JMP_BUF_SP is the index of a stack pointer slot in the __jmp_buf.
According to ARM __sigsetjmp code it does not depend on configuration
parameter __UCLIBC_HAS_FPU__. Make its definition unconditional.
__JMP_BUF_SP is used in the unwind_stop through the
_JMPBUF_CFA_UNWINDS_ADJ macro, this change fixes cleanup routines call
on thread cancellation in configurations with hard FP.

For some xtensa cores generated code gets arranged so that
__default_sa_restorer immediately follows preceding function. E.g.:
40a1b: c03340 sub a3, a3, a4
40a1e: f01d retw.n
00040a20 <__default_sa_restorer>:
40a20: e1a022 movi a2, 225
40a23: 005000 syscall
...
Contents of the .eh_frame section:
...
000007f4 00000014 000007f8 FDE cie=00000000 pc=0004076c..00040a20
DW_CFA_advance_loc4: 3 to 0004076f
DW_CFA_def_cfa_offset: 48
Due to the way xtensa libgcc uw_frame_state_for calls _Unwind_Find_FDE
for non-signal frames, FDE for the previous function is found during
thread cancellation signal stack unwinding in that case. Signal stack
frame is not recognized and is not unwound properly, breaking cleanup
routines calling for cancelled thread.
Insert padding before the __default_sa_restorer so that no FDE is found
for it, MD_FALLBACK_FRAME_STATE_FOR is called by uw_frame_state_for and
the frame is correctly recognized as signal frame.

Obstack was enabled in ARC defconfig to enable builds of native binutils and
GDB. This is not needed after earlier patch which removes invalid
_GNU_OBSTACK_INTERFACE_VERSION definition in cases when obstack is not
selected in uClibc configuration. With this change binutils and GDB would
use obstack implementation from their own source trees. In fact with recent
binutils it is not possible to build it using obstack implementation in
uClibc, because binutils/include/obstack.h started to use _obstack_free
function instead of obstack_free, but _obstack_free is not defined in
uClibc.

This is similar to this patch for GNU glob:
ff6ce3999db93a52d1cd22510f8508b660ddf54e.
The problem is that libiberty/obstack.c file checks for
_GNU_OBSTACK_INTERFACE_VERSION == _OBSTACK_INTERFACE_VERSION and elides
libiberty obstack implementation if there is already a compatible
implementation in libc. Therefore define should be set only when obstack is
actually selected, otherwise it is not possible to build binutils and gdb
with uClibc.

The FR-V port is really broken, and I have no emulator
or hardware for this platform. I tried to get some hardware
from RedHat, who made the FR-V port initially. Unfortunately
Fujitsi didn't agreed to sent me some of their unused spare
hardware lying @RedHat. As I invested some time to get stuff compiled,
I decided to add the code and may be anytime later I can gain
access to some emulator or hardware.
GDB simulator for FR-V doesn't support booting Linux AFAIK.

getaddrinfo() does not implement IDN encoding, and always fail when
provided an IDN flag (e.g., AI_IDN) with EAI_BADFLAGS. Some packages
(such as the VLC media player) check for AI_IDN before they use it;
providing an unimplemented AI_IDN in the libc makes these package
fail. As a result they make calls to getaddrinfo() with AI_IDN that
always fail while they could have made successful calls without AI_IDN
instead.
Thus, do not define IDN flags: it is better not to compile rather than
to compile a code that always fail.

ARCH_NATIVE_BIT should in the first place be passed when building utils
for host (BUILD_CFLAGS-utils). It could also be passed when building utils
for target (CFLAGS-utils), but this is actually not necessary
as ARCH_NATIVE_BIT and __WORDSIZE are identical in this case.
