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.

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.
