Not that I'm aware of. You'll probably want to wait until the patch to
implement it for regular links is submitted, though. It looks like it
won't be too long.

Are you planning on just eliminating unreachable local symbols, or
will you provide some way to identify a subset of globals to be
exported from the resulting output file?
