What about using "mmc -f ../library/*.m ../mdbcomp/*.m *.m" to generate a
Mercury.modules file in the slice directory which will cause mmc to read
the .m files in library/ and mdbcomp/ (instead of copying the files to
the slice directory)?

It would have to do more set the value of PLAIN_SUBDIR_MMAKE, since
there are some rules in slice/Mmakefile that would also need to change.
(my bootcheck failed, because I didn't revert the changes to
slice/Mmakefile).
