Hi Efraim,

Thank you for the review and feedback!

That's is a great new, I did not try to build it on any other OS or
platform. The reason I've add that flags is not a standard Makfile
coming with the project.

I would dedicate some time to figure out how to satisfy custom Makefile
to be compatible for larger range of systems available in Guix. Putting
to my TODO for 2024/02 updates.
