Yes, this can work. But Perl takes disk space on a uSD and it is a
sledgehammer to put a pin. On a small device with mainly a uSD, the less
space one takes on the uSD the longer it will run.

So, for "sysutils" packages (not all packages) the less dependencies,
the better (even if not cross-compiling).
