scripts/Mmake.rules:
Speed up `mmake --use-mmc-make clean' and `realclean' in the test
directories by calling `mmc --make' once for all the clean targets
instead of individually.
tests/hard_coded/Mmakefile:
Disable trans_intermod_user_equality test case when using mmc --make
as it requires --transitive-intermodule-optimisation.
