Earlier Darwin (esp. Darwin8 and Darwin9) had FAT libraries and suitable header
installations in /usr/include such that one could build a cross-toolchain 
(including cross-arch) using a common sysroot (including / for “current” version).

However this is no longer true on a number of levels.  A vanilla Darwin system has
no headers installed in /usr and it's certainly not appropriate to try and find
headers/libs for (say) x86-64-darwinNN X powerpc-darwin in /usr on any Darwin NN > 10 
(even Darwin10 is incomplete in that it omits the ppc64 multilib).  In the latter
example, the catch-all in the current configury to mean that 
"foo-darwin" == “foo-version-on-this-system” breaks the cross case 
—target=powerpc-apple-darwin —host=some-system-later-than-darwin10.
