Yes, I originally started with a configured GRASS plugin makefile to
create makefiles for other plugins. They're almost unrecognizable
now, and are tailored to compiling for the OSX framework (universal,
framework-only, no configure step), but could be easily extended to
support other systems.
Generally, get the OBJ list from the driver's GNUmakefile, and
discover the CFLAGS and LDFLAGS (include paths and external libraries)
needed for the format for your system by running configure as if you
wanted to build the formats into GDAL (values will be in gdalmake.opt).
Someone who knows autotools (or cmake) could make configurable
standalone source packages like the GRASS plugin.
