I'm lost. “Vanilla” 5.1.0 configured without --disable-checking went thru
stage2 w/o any issue...

            Bug ID: 66225
           Summary: libgcc/config/rs6000/morecore.S will not build on
                    systems with an older assembler
           Product: gcc
           Version: 5.1.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libgcc
          Assignee: amodra at gcc dot gnu.org
          Reporter: meissner at gcc dot gnu.org
  Target Milestone: ---
              Host: powerpc64-unknown-linux-gnu
            Target: powerpc64-unknown-linux-gnu
             Build: powerpc64-unknown-linux-gnu

I downloaded subversion id 223451 of GCC and tried to build it on my big endian
power7 system running Sles 11r3, and it would not build due to the use of the
.abiversion pseudo op that is not available in either the host assembler or in
the Advance Toolchain 7.0 assembler.
