Hi!
The python3.9 interpreter currently crashes on sh4 when built with -O2 or
better, building
with -O1 fixes the problem.
Could you therefore apply this change to debian/rules to unbreak python3.9 on
sh4?

I will try to track down which particular optimization flag causes the
miscompilation
and report the issue to GCC upstream.
