274895575e Add ARM EABI build attributes.
Ensure that all objects in ARM EABI glibc have the proper EABI build
attributes to indicate that 8-byte stack alignment is required and
preserved.  (GNU ld does not currently give errors for mixing code
requiring 8-byte alignment - such as anything built with GCC - and
code not marked as preserving it, because of the prevalence of
assembly code without proper markers to indicate that alignment is
preserved.  The ARM RealView linker does give such errors.)

The bulk of the markers are accomplished by the change to sysdep.h,
but a few .S files do not include sysdep.h.  In the case of
internal_accept4.S, no code is generated because EABI does not have
socketcall, but for completeness a dummy file with the right
attributes is used to override the default version in libc.

	* sysdeps/arm/sysdep.h: (Tag_ABI_align8_preserved,
	Tag_ABI_align8_needed): Attributes added.
	* sysdeps/arm/elf/start.S: Likewise.

be0f2008ac Implement new NPTL POSIX Threads ABI for HPPA.
This version of the NPTL POSIX thread ABI for hppa does
not break backwards compatibility with the the old
Linuxthreads ABI, and is therefore suitable for release
by distributions.

9d84a81fe9 Make accept4 for MIPS o32 avoid socketcall.
sysdeps/unix/sysv/linux/internal_accept4.S expects socket.S to be
present if __NR_socketcall is defined (which it is on MIPS o32, even
though there are separate syscalls as well) and __NR_accept4 isn't.
MIPS does not have socket.S, since it uses separate syscalls, but
though the accept4 syscall should be added soon present kernel headers
do not have it.  This patch creates a dummy internal_accept4.S for
MIPS o32, and an accept4.c wrapper that undefines __NR_socketcall so
that the main accept4.c falls back to the ENOSYS implementation if
__NR_accept4 isn't defined; it doesn't seem worthwhile to have a
special socketcall-based assembly implementation just for o32 on a few
kernels in the range between accept4 being available via socketcall
and the accept4 syscall being available.
