Factoring out numpy.distutils from numpy alone will not enable compiling scipy without numpy being installed. It probably can help, though, and might make sense also in view of the incoming deprecation of Python distutils (https://www.python.org/dev/peps/pep-0632/). Extension modules, including f2py, need numpy headers and probably also their platform-specific configuration. There are also some assumptions about data type sizes and Numpy versions at build-time being compatible with the ones at runtime, which factoring out distutils won't address. IIUC, cross-compilation is not actually supported, so that it can be made to work is surprising.
