Now that kunit.py's --kunitconfig is repeatable, let's create a file to
hold the various options needed to enable coverage under UML.
This can be used like so:
$ ./tools/testing/kunit/kunit.py run \
--kunitconfig=tools/testing/kunit/configs/all_tests_uml.config \
--kunitconfig=tools/testing/kunit/configs/coverage_uml.config \
--make_options=CC=/usr/bin/gcc-6
which on my system is enough to get coverage working [1].
This is still a clunky command, but far better than before.
[1] at the time of this commit, I get:
Overall coverage rate:
lines......: 11.6% (34112 of 295033 lines)
functions..: 15.3% (3721 of 24368 functions)
