I meant ld, not as. But that's rather unlikely to be helpful.

If that doesn't work, I wonder what else we can try linking to (I
solved the __divdi3 link error when I first saw it by linking to stuff
I saw gcc linking to until it went away). I wonder what this reveals
about libgcc installation across different Macs:
find /usr/lib -name libgcc*
