The 'xenfb' parameter for the '-vga' command line option is currently
always enabled unconditionally (since the xenfb is not a proper QOM
device that could be tested via its class name). That means it also
shows up if Xen is not enabled at all, e.g. like this:
$ ./qemu-system-sparc -vga help
none no graphic card
xenfb Xen paravirtualized framebuffer
tcx TCX framebuffer (default)
cg3 CG3 framebuffer
Let's avoid this situation by fencing the parameter with the
CONFIG_XEN_BACKEND switch.
