IFF the target doesn't support -Bstatic/dynamic  *and* doesn't provide a spec %{static-libstdc++:...
then, that could happen.

There's a fairly small group of non-binutils targets - other than Darwin that would be maybe AIX and some Solaris versions (and I believe that the native linkers there do support -Bstatic/dynamic), however, I'll double-check with the maintainers.
