I looked some more. What's happening is that this gcc driver adds
'--as-needed' at the beginning of the link command line. With that
--as-needed there, the problem reproduces with current trunk  binutils
(and probably any other version of binutils).

You should be able to reproduce this as well with:

  gcc -Wl,--as-needed ./foo.so t.c

P.S. To be clear, I don't care if this patch goes in after the hard
freeze is lifted, though it's trivially correct and may help anyone
with similarly configured GCC.
