config.guess includes darwin kernel major.minor.patch

[Patrick Mahoney]

Hello,

Not sure if this is a bug or intended behavior, but on Darwin 
config.guess
includes the output of `uname -r`, which seems to be the 
major.minor.patch
version of the darwin kernel.

I know of at least one set of packages, skalibs and related software, 
that uses
the output of `cc -dumpmachine` (which for clang and gcc, appears to 
come from
config.guess) to determine binary compatibility between platforms.

This test is too aggressive, since it means a program (execline) cannot 
be
compiled against a library (skalibs) that was itself built on a 
different
version of darwin, even though everything works just fine after
removing the test. See the discussion over at skalibs mailing list:

I'd appreciate your comments and insight.

Thanks,
