Yes, I agree that sysconfig._init_posix() has the proper logic for
this.  This logic should also be applied to Cython as well probably.

Would you say that the proper fix then is to inspect the Makefile and
set MACOSX_DEPLOYMENT_TARGET to the valued used to build Python
itself.  Or should we still try to set it to 10.3 in some cases (like
the current numpy.distutils does) or look at the environment as well?
