[PATCH] ppc32: Use -fPIC instead of -mrelocatable-lib

The ppc32 boot code has a couple of files that are executed very early
on before the kernel is mapped at the address it is linked at.  We
have been using -mrelocatable-lib to compile these files, but
apparently -mrelocatable-lib is deprecated and the gcc developers are
threatening to remove it.  In fact the -fPIC flag does what we need.
This patch changes -mrelocatable-lib to -fPIC.
