When building lang/python38 with QEMU, the build usually gets stuck with an
error like this:

Some times it also does not fail, which leads me to believe there might be =
some
sort of race
condition made visible by the use of emulation.
There are many ports fallouts demonstrating this issue:
https://portsfallout.com/fallout?port=3Dlang%2Fpython38%24
Unfortunately, as the bug causes the port to get stuck, this is very annoyi=
ng
to deal with.
Please investigate and perhaps mark as BROKEN when QEMU_EMULATING is define=
d.
