Any reason not to do it this way?

%{!?python_sitelib: %global python_sitelib %(%{__python} -c "from.
distutils.sysconfig import *; print (get_python_lib())")}

%{!?python_sitearch: %global python_sitearch %(%{__python} -c "from.
distutils.sysconfig import *; print(get_python_lib(1))")}

Also, dmalcolm, could we get these macros into the python and python3 (when
revewied) package so we don't have to add them as boilerplate to every
package?
