[Qemu-devel] [PULL v2 04/17] configure: error on unknown --with-sdlabi value

[Gerd Hoffmann <kraxel@redhat.com>]

From: Cole Robinson <crobinso@redhat.com>

I accidentally tried --with-sdlabi="1.0", and it failed much later in
a weird way. Instead, throw an error if the value isn't in our
whitelist.
