Hrm. It's been a while... I think you may actually have to rebuild GCC
with different configure arguments. Too much work just to work around
You could try instead manually preprocessing and generating that
single file using gas, with the g++ generated assembly continuing to
be used with the Solaris as. I have no idea if this will actually
work, though I don't see any reason why not.
$ cpp -Ibuild/include src/hash/sha1_amd64/sha1_amd64_imp.S | gas -o build/lib/sha1_amd64_imp.o
This patch might fix it, but it's a shot in the dark:

OK with that I am really off - don't expect further responses from me
before Thursday morning (GMT-5).
