Fix the failures in the PPC JIT by marking relocation entries for

external symbols (e.g. 'fmod') as needing a stub.  This regression
was introduced by Evan's jit patch here:
http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20071231/056749.html

With this fixed, the two ExecutionEngine failures are passing on ppc,
and the ppc jit works on freebench and olden.

This should be pulled into the 2.2 release branch.
