(svn r4102) -Backported 3673, 3674, 3675, 3679, 3682, 3882, 3884 [all OSX]
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
