I don't know the answer to this, but it seems to me that even if the
answer is "no", you could still obtain the symbol from bfd directly.
E.g, see bfd_lookup_symbol() in solib-svr4.c.  I doubt you'll need
to go to these extremes though.

You want to check for this symbol in your ${ARCH}_gdbarch_init function,
right?
