[Xen-devel] [PATCH v6] Autoconf: add variable for pass arbitrary options to qemu upstream

[Fabio Fantoni <fabio.fantoni@xxxxxxx>]

Added configure options for pass arbitrary build options to qemu
upstream.

Usage example:
./configure QEMUU_EXTRA_ARGS="--enable-spice --enable-usb-redir"

Signed-off-by: Fabio Fantoni <fabio.fantoni@xxxxxxx>
