[PATCH 5/5] configure: use kvm's configure usage for unknown options

[Carlo Marcelo Arenas Belon <carenas-kLeDWSohozoJb6fo7hG9ng@public.gmane.org>]

Prevent qemu's configure usage to be printed if an invalid option is
passed to it, allowing kvm's configure to trap those errors and print
the usage instead
