But it'd make it inconsistent with all the other lowercase variables
in Makefile.in that are acsubsted and not passed down to some child.

That's kind of stretching it.  :-)

I find the "extra" redundant -- the way I see it, some targets have a 
makefile fragment file that needs to be glued into the Makefile,
others don't.  There's no "main fragment, and then maybe some other/extra ones".

Why do you disagree?  ".mh" obviously meant "makefile + host",
but the fragment file is now described as being about the
native target.  Hence, "makefile + native => .mn".

I don't understand the rationale for renaming the file, saying it
is a native target fragment, but _still_ calling it ".mh".
So, I'd understand either not bothering to change the file name
at all, or if renaming it, then giving it a name that matches reality.

I really think the -extra suffix shouldn't be there.
