This is a good way to test that plist works.
Sorry for the large diff. There are a bunch of cleanups in here that
needed to be done. Should make it possible to use in cross
compilation.
Without this xcbuild can detect an incorrect version for store paths
that have a sequence of digits in their hash.
ld: malformed 32-bit x.y.z version number: 85294

This includes adding a new xcbuild-based libutil build to test the waters a bit there.
We'll need to get xcbuild into the stdenv bootstrap before we can make the main build,
but it's nice to see that it can work.
Also updates xcbuild version.
This changes the raw string expressions into nix expressions that are
then converted into json by builtins.toJSON. Then, converted to Plist
XML by Apple's plutil. Sadly, xcbuild does not support using raw JSON
but Apple's plutil does so we just convert the file from JSON to XML
using Apple's plutil. The result is not ideal but it looks like all OS X
systems have working plutil's.
- set mac version to 10.10
- add setup hook.
