Make sure "bash ./run" in the test directory still works and still runs the
test.

It works (modulo CL 7098046). It is hard to test that it "still works" due to
the lack of a verbose mode. I had to use:

(set -x;  F=dwarf; D=dwarf; G=$GOTOOLDIR/6g; L=$GOTOOLDIR/6l; A=6; source
testlib; rundir)

to be sure.
