This actually doesn’t make a huge amount of sense: something like
config.guess will return 'i386-apple-darwin10.0.1', despite the fact
that gcc will be (by default) targeting x86_64; anything which relies
on the knowledge that "i386" is by default entirely 32-bit will
therefore break. In contrast, most other x86_64 systems tend to be set
up such that x86_64 is reported as the “system” architecture (where
the kernel architecture is pretty incidental), and so you have a
triplet of, say, x86_64-pc-linux-gnu.
I’d be curious to know what would break if uname returned the
user-space architecture (as targeted by the system compiler by
default) rather than the kernel architecture.
