I had a failure with this step when using current GNU diffutils 
(3d1a56b906c31cc6e89f6a9c008ba54d734d4ec2, which has a gnulib submodule 
with Gnulib commit 99ce3a004a2974c71f510f5df5bc6be7e2811d30) with 
current Gnulib (5b6e410e04b48c0fd62e954fafa220ef301d2c70) and building 
on Ubuntu 23.10 x86-64. Build log attached. To reproduce, clone 
diffutils and then:

   export GNULIB_TOOL_IMPL=sh+py
   ./bootstrap
   ./configure
   make -k distclean
   git submodule foreach git pull origin master
   git commit -m 'build: update gnulib submodule to latest' gnulib
   ./bootstrap --no-git --gnulib-srcdir=gnulib

The problem is that the Python-based build leaves behind a __pycache__ 
directory, which causes the comparison to fail.
