Matthew Bauer a3a6ad7a01 stdenv: implement crossOverlays
crossOverlays only apply to the packages being built, not the build
packages. It is useful when you don’t care what is used to build your
packages, just what is being built. The idea relies heavily on the
cross compiling infrastructure. Using this implies that we need to
create a cross stdenv.

# N.B: the important thing here is to ensure that python == python2

# "PyThreadState_Get: no current thread". This is because Python gets
# really unhappy if you have Python A which loads a native python lib
# which was linked against Python B, which in our case was happening
# because we didn't override python "deeply enough". Anyway, this works
