--- Comment #12 from Martin Sebor <msebor at gcc dot gnu.org> ---
I see the same ICE on RHEL 7.2 with Binutils 2.23.52.0.1-50.el7 20130226 and
can confirm that switching to Binutils 2.27 lets the build proceed.  Among the
changes in auto-host.h between a 2.23 build and the successful 2.27 build that
look related to Binutils I see these:

HAVE_AS_COMPRESS_DEBUG            1           ->   2
HAVE_AS_ENTRY_MARKERS             undefined   ->   1
HAVE_AS_POWER9                    undefined   ->   1
HAVE_LD_COMPRESS_DEBUG            1           ->   3
HAVE_LD_PUSHPOPSTATE_SUPPORT      undefined   ->   1
LD_COMPRESS_DEBUG_OPTION          ""          ->   "--compress-debug-sections"
POWERPC64_TOC_POINTER_ALIGNMENT   undefined   ->   256
