xcodebuild is used in:
* prereq (where it fails harmlessly)
* python's spkg-install
* Mercurial's setup.py (upstream)
* the sage-bdist script

(Sage tip: use the rsyncable tarballs to grep all of Sage, including
spkgs.  Remember to create the top-level sage-VERSION directory yourself
and extract inside that.)
