New issue 3104: aarch64 pyyp 7.2 fails to use templating correctly when building numpy

mattip:

As reported in [numpy issue 14780](https://github.com/numpy/numpy/issues/14780), aarch64 cannot build numpy. It fails to properly convert \*.c.src files to \*.c files via the templating machanism numpy uses. Converting the files one-at-a-time works, but aal-at-once garbles the output. I am still trying to simplify the problem.
