make 'make test' able to run unit test harnesses

This adds a couple of make targets to do unit tests that are linked to
libc:

test-FOO : builds and runs test-FOO for any test-FOO.c
test : builds and runs all test-FOO tests

Note that building and running this test does not quite work yet /on
this branch/.  In order to do that, we need some cleanups and
reorganizing that I don't want to push just yet, which can be found on
https://github.com/rhboot/shim/tree/test-reorg
