[issue7473] x84_64 arch Missing from 2.6.4 Mac universal binaries - Cripples building embedded 64-bit

Ronald Oussoren <ronaldoussoren at mac.com> added the comment:

I don't agree that the current binaries are only useful for Tiger and 
earlier, the binaries work just fine on Leopard and Snow Leopard as 
well.

FWIW. I'm planning to provide a 3-way universal binary, or even just 
intel (i386, x86_64) for Python 2.7 and 3.2. That installer will only 
support OSX 10.5 or later.

BTW. I'll gladly review and patches that make it easier to compile a 3-
way univeral build without first removing the existing build. 

The reason that the current installer is not 3-way universal is that it 
is not possibly to have a 3-way universal binary that will run on 10.3.9 
or later unless you use different deployment targets for the various 
architectures and those different deployment targets cause observable 
differences in behavior because Apple fixed a number of Unix API issues 
for deployment target 10.5 (or later).
