I think just
mddump: ...
$(RUN_GEN) ... > mddump
will be sufficient. This is not actually used by the build at all, so we
don't need to play games with stamp files etc.
There's no need for top-level makefile changes at all. When you want to
use this, simply cd into the gcc subdirectory.

Why? Seems to me that you can just have genmddump.c simply use the
generic read_md_rtx interface, dumping as it goes. You might also
consider dumping the pattern_lineno argument as a comment before the
pattern. Otherwise it might be tricky to match up the dump pattern
with the original input file patterns.
