This patch makes -fpic work for PCC and optimzes the relcation by moving the cache
flushing stuff to JMP relocs only. Actually PPCs ldso can only handle small
GOT tables(<=8192 entries)anyhow, so it makes little sense to compile PPC with -fPIC.
libuClibc shrunk from 340724 to 330780 bytes with -fpic.
