ERROR: QEMU requires SDL or Cocoa for graphical output
To build QEMU without graphical output configure with --disable-gfx-check
Note that this will disable all output from the virtual graphics card
except through VNC or curses.
make[2]: *** [ioemu-dir-find] Error 1
make[2]: Leaving directory `/xen-unstable.hg/tools'
make[1]: *** [subdirs-install] Error 2
make[1]: Leaving directory `/xen-unstable.hg/tools'
make: *** [install-tools] Error 2


Configure correctly detects, there's no sdl installed but sdl support
is tried to be compiled nonetheless.
SDL shouldn't be compiled if only VNC is of interest.
