[Discuss-gnuradio] Modify Makefile.am in howto/src/lib/ to support templates

[Achilleas Anastasopoulos]

I was wondering if someone can slightly modify the Makefile.am in
howto/src/lib to include support for template expansion,
assuming the files generate_all.py and generate_common.py
(and maybe build_utils_codes.py, build_utils.py)
are present (in a similar way that is done in core/src/lib/general).

Right now, and since I have no idea how to do this,
I am manually running generate_all.py and then
manually adding the generated files into Makefile.am...

Thanks
