Thank you for your detailed info.  I think I was lazy, because I think
you have said all of it already.

I have no G4 machine to test on, only a G5, which might explain why it
works for me, and not for you.  I think the bootstrap script can be made
smarter, such that it detects ppc32 (`sysctl hw.optional.64bitops` ?) to
automatically insert this --disable-multilib configure flag.
