Commit 5f9b1e35060b8 remove the dependency between OpenGL and X11.
However the milkymist-tmu2 device do require X11.
When using SDL, the configure script sets need_x11=yes, so the X11
flags are populated to the makefiles.
When building without SDL, X11 is not pulled and populated, leading
to a link failure:
LINK lm32-softmmu/qemu-system-lm32

hw/lm32/milkymist-hw.h:114: undefined reference to `XOpenDisplay'

gmake[1]: *** [Makefile:199: qemu-system-lm32] Error 1
Enforce the X11 dependency when the LM32 target is built.
This will allow us to build QEMU without SDL.
