Well, make_filter actually calls make already. :-)

Seriously, one reason that I added it to the Makefiles in the
first place is that make_filter doesn't know what version of
make to use. Sure it is called make on almost all systems
and gmake (GNU Make) on most of rest, but since the user
knows and calls "make", $(MAKE) contains the correct "make".

Oh well, I guess just calling make will work on most platforms,
it will on all platforms that I current use. The Wine Makefile is
supposed to be portable so I guess it will have to do.
