bfd/ELF/PPC: make ppc_build_one_stub()'s stub_str[] static

There's no reason to have the compiler materialize objects onto the
stack.

In fact we can save some space and a level of indirection (and hence
relocation entries in the final binary) by converting to an array of
char[12] or larger. Pick char[16] for easier / faster calculations.
