For me (debian 10, python 3.8.3) this leaves __pycache__ in the top
directory. This is particularly unfortunate when configure is invoked by
"make clean"; I know, who runs clean first, except all debian packages

I tried adding a call to "cffi.verifier.cleanup_tmpdir()" per the cffi
docs, but there seems to be a nested __pycache__ directory that is not
cleaned up by that (or is created later).  I guess the best option is
just to rm -rf __pycache__ at the appropriate point in configure?
