#6414: OS X binaries should issue a better warning on incompatible CPUs

Currently, every now and then a user reports on sage-support, that he got
an error message like
{{{
/Applications/sage-4.0.1-OSX10.5-PowerPC-PowerMacintosh-Darwin/sage/
local/bin/sage-sage: line 198: 407 Illegal instruction sage-
ipython "$@" -i
}}}
This is e.g. the case if a Sage binary built on a MacPPC with a G5
processor (typically the one the OS X 10.5 bdist is created on) is used on
a MacPPC with only a G4 processor.
For the *nix world on Intel/AMD processors, the sage-flags.txt file was
created for just the purpose to check whether the CPU is sufficient, to
let a certain Sage binary run.
We seem to need something in that direction for OS X, too (though
momentarily only for the PPC processors, not the Intel ones).
