I am not sure I understand. I used ld. I verified with strace that there were
no other processes spawned. It just seems that ld was gold.

I mentioned -fuse-ld=bfd in my original post. It helped if I ran just the gcc
command line that linked .libs/libgp-sync.so. However, I am not sure how I
could pass -fuse-ld=bfd using configure/make. Adding -fuse-ld=bfd to CFLAGS and
LDFLAGS passed it to the libtool command line, but then libtool ignored it when
it actually invoked gcc for linking. It's probably a bug in the autotool
scripts.

Anyway, this being sad, my workaround was to rebuild the original binutils I
used to build the final binutils with --enable-gold=no. So, I'm good and don't
need support. I am merely passing on the information about the problem. It's up
to you, guys, what to do with it.

Best.
Andrey.
