  New compile error on ARM

Bug description:
  I have the following compile error with gcc-4.7 version
  4.7.2-23ubuntu2:

  /bin/bash ../libtool --mode=compile --tag=CC ../mpn/m4-ccas --m4="m4" gcc -std=gnu99 -c -DHAVE_CONFIG_H    -O2 -fomit-frame-pointer -D__GMP_WITHIN_GMP -I.. -DOPERATION_`echo udiv | sed 's/_$//'` -I. -I..  `test -f 'udiv.asm' || echo './'`udiv.asm
  libtool: compile:  ../mpn/m4-ccas --m4=m4 gcc -std=gnu99 -c -DHAVE_CONFIG_H -O2 -fomit-frame-pointer -D__GMP_WITHIN_GMP -I.. -DOPERATION_udiv -I. -I.. udiv.asm  -fPIC -DPIC -o .libs/udiv.o
  m4  -DHAVE_CONFIG_H -D__GMP_WITHIN_GMP -DOPERATION_udiv -DPIC udiv.asm >tmp-udiv.s
   gcc -std=gnu99 -c -DHAVE_CONFIG_H -O2 -fomit-frame-pointer -D__GMP_WITHIN_GMP -I.. -DOPERATION_udiv -I. -I.. tmp-udiv.s -fPIC -DPIC -o .libs/udiv.o
  tmp-udiv.s: Assembler messages:
  tmp-udiv.s:83: Error: ARM register expected -- `str r1,[ r0 ]'
  tmp-udiv.s:134: Error: ARM register expected -- `str r1,[ r0 ]'
  make[2]: *** [udiv.lo] Error 1 

  The problem occurs  trying to compile either mpir (upstream 2.6.0 or
  upstream trunk), or the ubuntu source package for libgmp10. The source
  file triggering the problem is in fact mostly the same.

  I think I can blame gcc rather than that source file because it used
  to compile when my toshiba ac100 was still running precise, then
  quantal.
