OK, I'll apply with this ChangeLog:

gcc:
    * config/elfos.h (MAKE_DECL_ONE_ONLY): Redefined to stop DECL_WEAK
    from being used for symbols with vague linkage when
    HAVE_GAS_COMDAT_GROUP is true.

This part of the patch has been reverted again for now, pending further investigation on ppc64 Linux, where it was causing libstdc++ build failure.

Cheers,

Julian
