Hi!

I've stumbled upon this beautiful little piece of software that let's
you generate FFT designs in Verilog.  Since it's free software I thought
I'd ready it up for my favorite distribution!

Thanks for merging!

You don't have to string-take, the standard pattern is (git-file-name 
name version), as in (guix)Version Numbers.

> +       `(#:tests? #f
Why are tests disabled?  There is a bench-test target, maybe you need 
#:test-target "bench-test"? I hope that means "test bench" and not 
"benchmark" though.

On the license: some parts are GPL3+ (see: 
https://github.com/ZipCPU/dblclockfft/blob/master/sw/legal.h), that 
sounds important to add to the license field to me (license 
(license:lgpl3+ license:gpl3+)).

Greetings,
Maxime.

I think (string-append "CXX=" #$(cxx-for-target)) is needed to, for 
cross-compilation.

Greetings,
Maxime.
