This fixes the issue for me on x86_64-w64-mingw32.

Note this is actually not target-specific; all targets that implement COMDAT
but not as weak symbols are affected. `decl_binds_to_current_def_p` already
contains a check for weak symbols, so the issue is invisible if COMDAT is
implemented as weak symbols, for example on Linux.
