(svn r3882) -Codechange: [OSX] changed the way universal and tripple binaries are build
Instead of compiling a binary for each arch and then join them in the end, each .o file is now compiled as a fat file
This means that the makefile will not call itself to make a binary for each target and we don't have to make clean between each build
it also means that if one file changed, we don't have to recompile all files
Another benefit is since it's handled at .o level and though LDFLAGS, no special code is needed if we decide to compile more binaries (like a lot of stuff used to happen at post linking)
We also needs much less flags to set up, so it should be even easier to get to work out of the box now
The tradeoff in doing so is that now the binary needs at least OSX 10.3.9 to execute
To deal with this issue, the JAGUAR flag can be used to compile for older OSes. We will release a binary for old OSes at next release to see if anybody even downloads it (not that many people use OSX 10.2 anymore)
GPMI will not work on 10.2 anyway so we will cut support for it some day anyway
