added support for G5 (ppc970) optimised code added support for triple binaries (ppc, ppc970, i386) updated the makefile to handle building of universal and triple in a more automated way (way less flags to set) now it's no longer needed to spent minutes setting up flags when releasing. It works out of the box :) note: even though it looks like it's a lot of commits, it really is that there changes were introduced in small pieces in the trunk
