bpo-45020: Drop the frozen .h files from the repo. by ericsnowcurrently · Pull Request #28392 · python/cpython
This is essentially an un-revert of gh-28375 (reverted in gh-28380). I reverted it due to a (single) buildbot failure. I've adjusted the code we generate for frozen modules in the makefile, based on a hunch about the make version, to fix it.
(Note that I also remove the frozen __hello__.h file, which I missed in the original PR.)
