common directory where SHMLBA = __getpagesize()
This patch fixes the issue.

containing an object built without -fpic/-fPIC - then:
* If __FORCE_SHAREABLE_TEXT_SEGMENTS__, then it gives an error "Can't
modify %s's text section. Use GCC option -fPIC for shared objects,
please.\n" and exits.
* Otherwise, it makes the library's pages writable and relocates it.
If it encounters text relocations in a position-independent executable -
one containing an object built without -fpie/-fPIE/-fpic/-fPIC - then:
* If __FORCE_SHAREABLE_TEXT_SEGMENTS__, it does nothing about making the
pages writable, leading to a crash.
* Otherwise, the loop to make the pages writable uses the same variable
ppnt as used in an outer loop, messing up that outer loop and also causing
a crash.
This patch fixes both cases, by giving an error if
__FORCE_SHAREABLE_TEXT_SEGMENTS__ and saving and restoring ppnt otherwise.
Tested in both cases on ARM EABI.

On cygwin one has to pass
make menuconfig HOST_LOADLIBES="-lcurses -lintl"
otherwise just curses is linked in and some symbols that live in intl are
unresolved. Closes #1554 and possibly a couple of other reports.

The attached patch solve an issue I faced while using the libdbus-glib
waiting for a D-Bus message or the end of a glib timer at the same time.
This specific case of use generate a poll call with a zero timeout. On
platformes with the glibc a zero timeout poll return immetiately even if
there is no file descriptor event. But on platformes with uClibc a zero
timeout poll block until a file descriptor event occurs.

will set the type of common symbols to STT_COMMON
instead of STT_OBJECTS, so the dynamic linker needs
to handle this type os symbols too.
Same changes have been added to glibc (See: bugzilla #5104).
This patch ensures the uclibc will work with later bintuils.

- adjust setting flags accordingly to use (hardcoded, see below) -Wl,
Potential improvements:
*) --warn-unresolved-symbols should perhaps be used for all libs
*) eventually rename LDFLAGS to CC_LDFLAGS
*) probe for compiler driver's notion of flag to use for passing in
linker flags (i.e. don't hardcode "-Wl,")

This wants a stub_enosys(readahead) line later on, like many, many others need..

IPv6 entries in /etc/hosts. Previous only the first of these host would work,
as uClibc would read the /etc/hosts file from top to bottom, failing if the
first hit did not match the IP type.
Now uClibc will continue reading, even if the first correct entry name, but wrong IP
type fails. Thus, allowing a second correct entry name with correct IP type
will result in a name resolve.

GCC 4.3 will put fixed headers in a seperate include-fixed directory.
And I don't think that there are people who are still using the 'stupid'
GCC which cannot handle -iwithprefix, at least it works with gcc-3.3.x.

thus need to initialize stuff with 0 to force it into bss.
All hell can again break loose if future gcc will be smart enough
to ignore it.

I got the library to compile with the attached patches, though dynamic
loader crashes early.
In buildroot I changed the architecture name by hand from sparc to
sparc64, otherwise the compiler produced 32-bit files with V9 (64-bit)
instructions. This configuration is not supported by QEMU, so I aimed
for pure 64-bit. I think Sparc64 option needs to be added to
buildroot.
The _Qp_ ops seem to be required by the ABI. This and setjmp patches
are just hacks to get the compilation further. The _Qp_ ops can be
found in glibc, would it be OK to use those?
V9 assembler requires declarations for global register use.
The mem* functions in sparc32 directory did not work. They are
actually used only by the hybrid 32-bit + V9 CPU configuration.

In MIPS syscall(2), .cpload was added to an the error path, but it was
not enough for ABIs other then O32. Use SETUP_GP, SETUP_GP64 and
RESTORE_GP64 to handle all ABIs. This patch fixes an error path of
MIPS pipe(2) too.
