We'll have conflicts around CFLAGS, the nolibc-test target and probably
other things. It will also make everything harder to understand and may
break unexpectedly in the future.

Is your issue specifically with the help target?
We should be able to show the help message from the main Makefile with a
hint to the Makefile.nolibc.

Another, more general, possibility would be to move the special Makefile
to tools/testing/nolibc/ and keep only the selftest parts in
tools/testing/selftests/nolibc/.
