AFAICT, GNU_UNIQUE was added in glibc-2.11 in 2009:
  0122f28eb (Ulrich Drepper 2009-07-21 08:32:54 -0700  872) *
STB_GNU_UNIQUE support added.

That is only a year after public release of Gold. Also, gcc/configure
tests for support for GNU_UNIQUE, and doesn't emit it if the target
libc doesn't support it. So I am not sure how you could run into
problems here. But you may well be correct ;-)
