Do not terminate default test runs on test failure

That means that some dependency of the toplevel tests target failed 
(possibly because a test failed to compile), in which case the commands 
for that target don't get run.  Generation of summaries relies on 
dependencies not failing - there is a presumption that while some tests 
may fail on execution (which doesn't translate to a make-level failure 
unless stop-on-test-failure is set) for reasons that are hard to fix, any 
failure to compile is a serious problem that should also be 
straightforward to fix.

So find what the first failure at make level was and fix it (or add it to 
$(tests-special) and use $(evaluate-test) in the rules, if it really needs 
to be counted as a test that's allowed to fail).
