gmake does set MAKE correctly.  You can test that with a simple
Makefile like:

all:
	@echo ${MAKE}

The problem is that the code Makefile runs "make -C $(BUILDDIR) $@
$(MAKEFLAGS)".  MAKEFLAGS is not meant to be passed on the command
line like that because it doesn't contain command line flags.  It only
contains single letters so "d" instead of "-d".
Bmake sets this to "w" when it calls gmake like gmake does for its own
submakes to get Entering/Leaving messages.  This happens in do-build
with USES=gmake.

With the attached patch the port still builds for me.
