Python failure in poudriere on arm64 (via qemu-user-static cross compiling)

Hi,

I recently see a strange failure with python 3.9 in poudriere, it was 
not happening a few weeks ago.

I'm building in poudriere on a head machine running amd64, with a 
poudriere jail for arm64, via qemu-user-static. The jail is running 14.0.

I'm not sure what is going on.

It fails in the packaging phase with a bunch of errors like:

===========================================================================
=======================<phase: package        >============================

(it's all about 'opt-2.pyc' files)


What could have changed? Maybe I'm doing something wrong? Maybe I'm 
hitting some qemu-user-static issue on head?


Any help appreciated.
