The configure check doesn't verify the python version. Does
--enable-generated-files-in-srcdir (used when building release
tarballs) generate the required section so it's packed up in the
release tarball and avoid requiring python3 when building from the
release tarball?
Note these kind of dependences should be mentioned in
install.texi - for python also listing required modules would be nice.
Thanks,
Richard.

The python script would have been more informative, the generated
.texi fragment and the Make-lang.in part as well

[PATCH v4 1/19] modula2 front end: changes outside gcc/m2, libgm2 and gcc/testsuite.
While writing the ChangeLog entries git gcc-verify spotted an oversight
with v3 of this patch set. I had forgotten to post gm2.texi and also a
tiny patchlet in gcc/configure.ac (to detect Python). HAVE_PYTHON is
used within gcc/m2/Make-lang.in to avoid generating the library section
included by gm2.texi should Python not be available.
ok to commit? I've included gm2-lang.cc and lang.opt for reference.

Gaius
