The following patch Implement a configure passthrough for qemu and
migrate all current qemu specific configuration flags (enable-alsa,
disable-vnc-tls and disable-gcc-check) to use it.
It uses qemu's configure to get a list of hints for additional options to
use and to keep backward compatible descriptions with what was used before
(adding disable-gcc-check statically with its warning about using gcc4).
