I do not think there is a workaround.  This seems to be a regression
introduced by this commit:

commit 825adeeed1e95990fd1efb70d9ac3eb7f1ea802a

    Mark __dso_handle as hidden [BZ #18822]

    Since __dso_handle is always defined by either crtbegin.o from GCC or
    dso_handle.c, it should be marked as hidden and be passed directly.

Would you please file a bug here?

Maybe the link editor could be a bit smarter about this, but that's a
different conversation.
