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.
	* sysdeps/arm/eabi/abi-note.S: New file.
	* sysdeps/unix/sysv/linux/arm/eabi/internal_accept4.S: New

fbc4c20a80 Fix register conflicts and avoid deprecated instructions in ARM EABI setjmp/longjmp.
* setjmp and longjmp were using the obsolete fstmiax and fldmiax
  instructions.

* Because of a confusion with two different sets of names for the same
  registers (r0...r3 and a1...a4), if VFP was present then the
  subsequent check for iWMMXt support would use a register that had
  been clobbered by saving/restoring the VFP registers.  (The bit
  being checked was clobbered by a reserved bit of FPSCR that it
  always 0 on present hardware, and no present hardware has both VFP
  and iWMMXt, so this did not cause visible problems.)

            Julian Brown  <julian@codesourcery.com>

	* sysdeps/arm/eabi/setjmp.S (__sigsetjmp): Replace deprecated
	instruction fstmiax with vstmia.
	Correct register conflict and comment.
	* sysdeps/arm/eabi/__longjmp.S (__longjmp): Use vldmia not fldmiax.
	Don't clobber r1/a2 register before testing IWMMXT hwcap.
