Thanks for this package.

Either in the Config.in help text, or in package/mfgtools/readme.txt.
We have already mentioned such a possibility for another package, and I
think we should start doing it.

As a follow-up patch.

Please use:

MFGTOOLS_CFLAGS = \
	... \
	... \
	...

Please remove the space between -l and the library name. Also
-Wl,-rpath=$(HOST_DIR)/usr/lib is already part of $(HOST_CFLAGS), so
you can get rid of this part.

This build system is really completely brain-damaged. I would suggest
to instead use the host-cmake-package infrastructure with a proper
_SUBDIR so that it builds the library, and then a simple post-build
hook to build the CLI tool.

And of course, submit a bug report upstream to tell them to use CMake
for the whole thing rather than doing this crap.

Full destination path needed when using $(INSTALL) -D.

Thanks!
