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:

Unfortunately, as the bug causes the port to get stuck, this is very annoying
to deal with.
Please investigate and perhaps mark as BROKEN when QEMU_EMULATING is defined.
