It seems that ‘command-line’ is unbound here, no?

I was wondering: if the only thing that differs between Linux and Mach
is the command line, could we keep the same activation script for both
cases, and instead move the conditional to (gnu build activation), like:

  (if (string-contains %host-type "linux-gnu")
      linux-command-line
      mach-command-line)

Does that make sense?

Thanks,
Ludo’.
