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.

The Darwin pic base loads (and reloads for non-local-gotos) are not
validly copied (since the pic base label would be duplicated). Thus,
mark the pic base {re-}loads as non-copyable.
