Not from me.

While it is more usual to run the test via the bootcheck script, there
are a couple use cases for being able to run them directly:
1. Where the compiler cannot be bootstrapped in the grade you are
testing. That's not currently much of an issue, but it has been
in the past and may be again in the future.
2. Where you want to test an installed (i.e. not stage 2) compiler.

I think the commit that broke it was either afe2887 or 520ce39 since
they are the ones that changed the value of TEST_DIRS to hardcode it
The problem being that when you now do "mmake runtests" in the tests
directory itself, it looks for various files in the top-level of
the the source tree, rather than in the tests directory itself,
Mmake.common:82: ../DEFNS_FOR_TESTS: No such file or directory mercury_compile:
cannot open ../TESTS_FLAGS: can't open input file: No such file or directory
mercury_compile: cannot open ../TESTS_FLAGS: can't open input file: No such file or directory
gmake: *** No rule to make target `../DEFNS_FOR_TESTS'. Stop.
