[PATCH] qemu: fix nativesdk build without x11

[PATCH] qemu: fix nativesdk build without x11

[Eric Bénard]

when x11 is not defined in DISTRO_FEATURES, there are no x11 headers
so True is not defined leading to :
| ui/sdl.c:62:8: warning: type defaults to 'int' in declaration of 'doing_grabs' [-Wimplicit-int]
|  static doing_grabs = True;
|         ^
| ui/sdl.c:62:22: error: 'True' undeclared here (not in a function)
|  static doing_grabs = True;
|                       ^

Does qemu on SDL on framebuffer actually work?  I'd assumed that
people using qemu without x11 were using it without SDL, so maybe this
is a bug in the build configuration for nativesdk.

A better fix would be to use 1/0 instead of True/False, I was assuming
that SDL meant X was being used.

I'm not using qemu in the present case, I was simply building a sdk.

that would also fix the problem.
