I found the following code (commented out) in one of my setup scripts.
It might do what you want, but it is untested:

from distutils.command import build_py

# a class which will allow to distribute packages *and*
# modules with one setup script, currently unused.
class my_build_py(build_py.build_py):
    def run (self):
        if not self.py_modules and not self.packages:
            return

        if self.py_modules:
            self.build_modules()
        if self.packages:
            self.build_packages()

        self.byte_compile(self.get_outputs(include_bytecode=0))
    # run ()
