So my make-foo isn't very strong, but no objections from me.

My only thoughts:
1) Would it be better if threadtest can be made to have better
defaults for kselftest so you don't need that extra logic?
2) While I get that TEST_FILES is likely going to be used to copy the
destructive tests over, It feels a little like its being bundled in
with something like data files that tests might need, which seems sort
of hackish. Would TEST_PROGS_EXTENDED or something be more clear and
make more sense?

thanks
