I think that the main mistake here is that I kept the code in
tst_vbrk_() that exits the test with a return value in the case of a
child processes. So ideal fix would be to change the test library not to
do that, but that would require a bit more work, especially we would
have to look at all WAITPID() usages in newlib tests and make sure that
there are not tests that depends on such behavior. If there are none it
would stil require a few changes in the test library.
