Re-enable pie support on macppc (still off by default but usable
again). Due to the way executable sections are loaded by the kernel, a one page .got section with the blrl instruction may be in the data cache and not flushed causing random crashes upon process startup. Flush the data cache before ___start() jumps there. Also mprotect the .got section to be read/exec instead of read/write/exec. ld.so knows how to cope and static binaries don't write to .got. written by and okay drahn@
