In various places in the code, it's assumed that the __POWERPC__ define is Mac OS 9 specific, but our clang defines it as well, breaking the build, revert to the gcc situation. Also add a license marker (thanks to jca@ for figuring out under which license we should distribute it), and remove MASTER_SITES because it can't be fetched from upstream; this port may be removed soon or otherwise its distfile mirrored. OK sthen@ and jca@
