Managed to build it after hacking configure to use pkgconfig.  Patch 
attached for reference.

Same bug as SDL on framebuffer:  No sane console switching.  Boot a 
guest, switch to another (host) virtual terminal, watch qemu continue 
drawing on your screen.

Guys, this is simply not acceptable.  You are not alone on the machine. 
  If I switch away to another virtual terminal I want to see that other 
terminals content and nothing else.

NACK.

cheers,
   Gerd
