Power 8 was once again having build issues. Adding --with-system-zlib
fixes them. It seems the builtin one is only needed when you are going
to build programs, and it falls apart in other cases.
Searching --with-system-zlib reveals this to be a very popular topic.
This has not broken other toolchain builds (for me); it should not for
anyone else. Then again, this is gcc, about which I need say no more.
