I would make this something like

> +           (lambda (#:key tests? #:allow-other-keys)
> +             (when tests?
> +               (invoke "./cm256_test")))

Then "guix build --without-tests=cm256cc cm256cc" can be used
for building "cm256cc" without tests, and the "cm256_test" 
binary won't be invoked when cross-compiling.

(I assume it is a binary.)

For testing cross-compilation to aarch64-linux-gnu:
  ./pre-inst-env guix build --target=aarch64-linux-gnu cm256cc

Greetings,
Maxime.
