That python script works across gcc/binutils/gdb:
https://sourceware.org/cgit/builder/tree/builder/containers/autoregen.py

It is installed into a container file that has the exact autoconf and
automake version needed to regenerate the autotool files:
https://sourceware.org/cgit/builder/tree/builder/containers/Containerfile-autotools

And it was indeed done this way because that way the files are
regenerated in a reproducible way. Which wasn't the case when using --enable-maintainer-mode (and autoreconfig also doesn't work).

It is run on all commits and warns if it detects a change in the
(checked in) generated files.
