(svn r3674) -Feature: [OSX] Added support for tripple binaries (binaries optimised for G3, G5 and i686) G4 have no problems using G3 code while G5 can, but really benefit from getting their own optimised code (Apple: G5 is not just a fast G4) Also changed FAT_BINARY to UNIVERSAL_BINARY since Apple removed most (all?) references to fat binaries on their homepage two days after I added FAT_BINARY

 # Special for crosscompiling there are some commands available:
 #
-# FAT_BINARY: builds a universal binary for OSX. Make sure you got both PPC and x86 libs. Only works with GCC 4 or newer
+# UNIVERSAL_BINARY: builds a universal binary for OSX. Make sure you got both PPC and x86 libs. Only works with GCC 4 or newer
+# TRIPPLE_BINARY: builds a universal binary with the addition of code optimised for G5 (which means a total of 3 binaries in one file)
 #
 # JAGUAR: Crosscompiling for OSX 1.2.8 (codenamed Jaguar). Only works if OSX is defined too. Only works with GCC 4 or newer
 #	This can be changed to any PPC version of OSX by changing the ppc flags in Makefile.config
