I don't think it's a general problem.  What's odd here is that the
system compiler is requiring a library which gcc doesn't link against.
That is uncommon.  Usually we just make gcc link against the
appropriate libraries, by putting them in LIB_SPEC.

I see nothing wrong with this.  It's just tedious to implement.  The
bootstrap operation currently executes entirely within the gcc
directory.
