Add -Bsymbolic-functions to XDT_FEATURE_LINKER_OPTS.

Although removing the visibility checks from several modules makes the whole
thing easier to understand, it does increase the PLT overhead a bit.
Fortunately recent versions of ld support -Bsymbolic-functions which will
decrease PLT overhead of shared libraries.

It works fine here and I think it safe to use (also used by OOo). -Bsymbolic
however could result in problems, so better not touch that.
