[issue22359] Remove incorrect uses of recursive make

[Martin Panter]

Martin Panter added the comment:

FWIW two times recently I saw strange intermittent build errors. I use “make -j2” on Linux. The one time that I investigated was a Python module (math or cmath perhaps?) failing to build because some dependency was zero bytes, and looking through the build log, I saw duplicate compiler commands lines printed out one after the other to build that dependency.
