The only way is to use a newer ld.

Sadly, bfd doesn't really distinguish between warnings and errors when it comes
to printing, so there's no "-w" flag as for gcc.

I suppose we should just disable this test by default for now.  I'll note that
despite the warnings, you got a binary that runs as expected.
