I suspect that the stream of errors starts with something like:

	foo.c:1:23: error: grass/gis.h: No such file or directory

When faced with a large number of errors, always look at the first
ones, as they usually indicate the actual problem, while later ones
are merely symptoms of the problem.

Also, always redirect "make" output to a file, e.g.:

	make &> build.log
or:
	make 2>&1 | tee build.log

It's probably because include/Make/Platform.make has GRASS_HOME (etc)
pointing to the directory where GRASS was built.

If you want to compile add-ons against an installed version of GRASS,
you'll need to override more than just MODULE_TOPDIR. AFAICT, you may
also need to override ARCH_DISTDIR and ERRORLOG and possibly
ARCH_BINDIR and/or RUN_GISBASE.
