As with the cpython-apple-source-deps repo, this should likely be configured as a separate TARGETS-MacCatalyst et al.

Added the MacCatalyst target as suggested

Why are these options needed? The CPython makefile should be setting all these correctly

I think it's required when building C++ targets in mobile-forge (e.g. numpy). Without this I wasn't able to get that to compile. However, let me double check on this and confirm once I've addressed the other comments.

If it's C++ targets that are the problem, that seems more likely due to either (a) the clang++ shims not existing, or (b) the clang++ shims not being on the path when mobile-forge is running.

Yes you were correct, I've resolved this issue now with the correct configuration of the shims
