TLS_LD should use linker-provided symbol _TLS_MODULE_BASE_ instead of
symbol it resolves to get thread pointer, otherwise linker relaxation
doesn't work correctly, adding extra offset to thread-local variable
address.
This fixes most of tls/tst-tls* tests.

Native gdb makes a ptrace (GET_THREAD_AREA) which needs to return the
TP. however when libc sets up TP reg (for main thread), it doesn't call
arc_settls syscall so kernel doesn't know of TP register details
(moreso because clone doesnt have SETTLS flag)
Note that kernel doesn't know about r25 being TP etc.
This commit got lost in merge of NPTL tools into arc-mainline-dev and
showed up again as STAR 9000919529 (native gdb can't debug threaded
apps)

ret_ERRVAL is used by mq_timedsend and mq_timedreceive, it needs to be
defined to retw, otherwise error return from those functions segfaults.

Cancellable syscalls use call8 to call functions that enable/disable

Redefine FRAMESIZE for such syscalls.

These days IPv6 is used more and more in different software
packages. And so we're adding IPv6 support by default in uClibc
for ARC cores.

uClibc doesn't define signal info for the SIGSYS signal which is issued
in case of hitting a syscall prohibited by seccomp.
This is sad as it makes debugging seccomp filter policies impossible on
some architectures (at least ARM and PowerPC, maybe also others) which
do not coincidentally set si_value.sival_int as the syscall number.
To fix this, import the definitions and macros needed from glibc.

When attempting to build uClibc under buildroot, including building the
tests, the silly tests don't currently compile, a result of attempting
to build using a compiler that does not yet have an installed version of
uClibc available. The error is a missing header file, specifically
atomic.h.
Taking inspiration from the nptl tests, I have extended the EXTRA_CFLAGS
variable to add the required include paths. The tests can now be built
under buildroot.

The current code implements the 'm' modifier only for 's'
conversions and would cause a segfault if it was used for 'c'
or '[' conversions. This patch extends the code to cover these
cases too.
The original version could write scanned data outside the passed buffer
because index i used in the '[' conversion handling block was clobbered.

(__pthread_initialize_minimal_internal): Initialize pd->report_events
to that.
This patch helps NPTL report TD_CREATE event, so that GDB could catch the
event and update its thread_list.

Previously V=1 did print abbreviated commands and V=2 the full commands.
Kbuild-based build-systems behave in the opposite way and this is
apparently confusing or inconvenient for users so swap our V handling to
be in line with kbuild (and automake as far as V=0 / V=1 is concerned).

etc so enable that too
Enabling mentioned options to make sure more packages could be built with ARC pre-built uClibc tools.
Note UCLIBC_USE_NETLINK is a prerequisite for UCLIBC_SUPPORT_AI_ADDRCONFIG.
