don't run the test binaries, compilation status is enough

During a cross-compilation we can compile the test binaries but not
run in the host machine.  Furthermore, the exit status of the test
isn't really important for the types of check we have, the compilation
status is enough.

Reported by Nikolay Korotkiy (@sikmir) on Github, fixes issue #8
