I always use -v 4 as argument to guix. I do not remember whether 3 or 4 is the 
biggest effective value. You could try with that.

About the warnings of invalid argument list: comment out the argument lists in 
the toolchain packages (I do not remember fully the names, I do not have acces 
to the big computer right now for easy reference). See how the change effects 
the build.

I learned a lot by intentionally breaking code and reading the errors.

Sincerely,

Marek
