My intent was to make it work "out of the box" in the same way as
SHELL_PATH does now. So that:
echo TEST_SHELL_PATH=whatever >>config.mak
make test
cd t && ./t1234-*
both respect it. Without going through BUILD-OPTIONS, I don't think it
makes it into the environment via config.mak (it _does_ if you specify
it on the command-line of "make", though).
For my purposes it would be fine to just use the environment, but I was
trying to have it match the other variables for consistency.

I'm not quite sure what this is fixing. Is there a case where we
wouldn't have TEST_SHELL_PATH set when running the tests? I think there
are already other bits that assume that "make" has been run (including
the existing reference to $SHELL_PATH, I think).
