boehm-gc/gc.h doesn't define DYNAMIC_LINKING for PPC Linux.  This
causes problems.  I have a patch for this that I'll check in later.

It might have originated at Cygnus, but it isn't just a Cygnus thing.
multilibs are used to allow a single compiler to generate code for
multiple ABIs (e.g., both little- and big-endian MIPS).  In this case
the target libraries are configured for each commonly-used ABI.

I tried an alpha linux build yesterday but it didn't multilib for me.
