The gmake54 script which is present when you use --disable-gmake
(which is the default for 5.4.0) doesn't use Gmakefiles. It uses the
makefiles which are built by "make makefiles" (which is the first step
in the build process).

Essentially, it won't work with anything which is outside of the GRASS
source tree. If you want to build add-on modules, you can either:

a) use "configure --enable-gmake ...", to use the old build system,

b) place your source code inside the GRASS source tree (then,
"make makefiles" will automatically build a makefile from your
Gmakefile), or

c) write your own Makefile which doesn't rely upon the GRASS build
system, and just run "make".
