This is just a specific instance of the problem where alternatives may
not be what you want.  The busybox test suite should be sure it's
running busybox tools.  Having spoken to a few people about this
already, maybe busybox-ptest should contain a symlink farm for all the
applets to the busybox binary that run-ptest can put at the front of
$PATH.

Let's fix the hostname setup so hosts is correct too.
