[Qemu-devel] [RESEND] [PATCH] show usage and abort if unknown option is passed to configure

[Carlo Marcelo Arenas Belon]

Any comments on this?, is ignoring unknown parameters to configure a feature
as I suspect to prevent build failures on users that assume that it is
autoconf based and try to enforce the defaults with an unknown option like
--enable-sdl?

The following patch prints an error if an unknown option is passed to
configure and directs the script to show usage information.
