Only running simple tests is preferable to running no tests at all.  If
you think that unvendoring everything is an unreasonable amount of
work, that's a viable solution.  However, we do strive to offer
complete packages, so feel free to do 1. :)

If you need some pointers as for the test files, ppsspp includes both
another package's source (not so great, needs better unvendoring) and
test files, and there's probably some other packages you could consult
as well.

Note that python is now missing from native-inputs, but python-lit is
in there.  I suppose you need python both as input (for linking) and
native-input (to run whatever python-lit is supposed to do).
