I would expect us to use an environment variable or command-line
switch (perhaps with RUBYOPT) to allow testing to work.

mkmf works fine with everything in ext/ without install, so I
expect mjit to work, too.  I will let Nobu figure it out.

load-relative seems to work, but that leads to a bigger problem:
it can break my normal runtime ruby installation when I'm hacking
on the source tree I install from.
