Bootstrapping with
GDCFLAGS_FOR_TARGET='-O2 -g -fdump-tree-optimized -da'
didn't show the comparison failure.

That didn't show the failure either.
To make things even more weird, I've run several regular bootstraps
since:
* Friday night:
** Solaris 11.4 trunk (latest development build, bare metal, SPARC-S7):
32-bit gas/ld and 32-bit gas/gld bootstraps failed with the comparison
failure, while 64-bit gas/ld completed.
** Solaris 11.4 (latest update, kernel zone/VM, different host,
SPARC-T5): 32-bit gas/ld failed.
** Solaris 11.3 (latest update, kernel zone/VM, SPARC-S7): 32-bit gas/ld
failed.
* Monday night: 32-bit gas/ld bootstrap passed.
* Tuesday night: 32-bit gas/ld bootstrap failed again.
Seems incredibly fragile, unfortunately.
