Do not terminate default test runs on test failure

Apart from needing make -k being unnecessarily different from normal 
conventions for how testsuites work, it also doesn't work for getting the 
test summaries: if any tests (dependencies of the tests target) fail then 
the makefile rule for the tests target (which in a subdirectory generates 
subdir-tests.sum, and at toplevel also generates tests.sum) doesn't get 
run.  The point of this patch is to generate a normal summary file of test 
results at toplevel, regardless of whether individual tests passed or 
failed - so you don't need to use -k and postprocess make output to 
identify failures.
