I committed a simpler version of this patch. After rB2c23b4e0bff0: Python: on macOS, stop requiring framework for building bpy module it defaults to using Python from the precompiled libs where no extra code to detect the real Python exe is needed.

Maybe this will still fail when building Blender against a system Python install, though even that I could not reproduce and there's not really any reason to even do that. So not worth having this code complexity I think.
