I think this patch causes spu-elf to fail to build:

/home/apinski/src/local/gcc/libstdc++-v3/libsupc++/typeinfo:169:
error: creating run-time relocation for '_ZTISt8bad_cast'

Before we did not compile with -fPIC at all but now are trying to
compile with -fPIC which fails when there are runtime relocations
because right now spu-elf's loaders don't support runtime relocations.

You can easy reproduce this bug with a cross to spu-elf.
