The macros must be defined prior to evaluating config.h, since
test_config.h needs them.
Also define an uppercase version of the PROJECT variable, so that we
define TEST_FOO in addition to TEST_foo.
BUG=chromium:322144
BRANCH=none (but might need it if you later cherry-pick something with
an uppercase #ifdef BOARD_FOO
TEST=Build each board with V=1 option: 'make V=1 BOARD=foo all tests'.
Check that the compile command line has both mixed-case and
uppercase defines. Check that per-board tests from test/build.mk
were built (for example, BOARD_PIT should compile kb_scan and
stress, and BOARD_SAMUS should build none of them).
