Make sure the phase returns #t on success:

  (and (zero? (system* "make" …))
       (begin
         (copy-file …)
         #t))

Does it build both on GNU/Linux and GNU/Hurd?

We probably need a ‘supported-systems’ field to restrict to i686 and
x86_64(?) GNU/Hurd and possibly GNU/Linux.

OK with these changes, thank you!
