9b9c37c364 ("tcg-sparc: Assume v9 cpu always, i.e. force v8plus in
32-bit mode.", 2012-09-21) removed the need for this variable and
most of the references to it, but this one.

Remove defunct code, no effect or functionality change expected.

[Qemu-devel] [PULL 04/14] configure: fix sdl detection using sdl2-config

[Laurent Vivier]

From: Carlo Marcelo Arenas Belón <carenas@gmail.com>

If SDL2 is requested but pkg-config doesn't have a module for it
configure should fallback to use sdl*-config, but wasn't able to
because and old variable (from SDL) was being used by mistake.

Correct the variable name and complete other related changes so
there are no more references to the old SDL.

[Qemu-devel] [PULL 13/14] hw/display/sm501: Remove unused include

[Laurent Vivier]

From: Philippe Mathieu-Daudé <philmd@redhat.com>

The "cpu.h" include makes devices target-specific. Since it
is not used, remove it, so the device become generic (we can
now compile it once for all targets).
