LGTM (though, supposedly we want similar change in
libstdc++-v3/testsuite/Makefile.am).
Or, if people would really like to see the commands, we could print them
just once, using e.g.
	-$(if $(check_p_subno),@)(rootme= ...
(then e.g. check-parallel-gcc goal would print the command, but
check-parallel-gcc-1 or check-parallel-gcc-112 would not).
