[Qemu-devel] [PATCH 1/3] Check for sdl-config before calling it

["Loïc Minier" <lool@dooz.org>]

Check whether sdl-config is available before calling it, otherwise
./configure triggers a warning:
    ./configure: 957: sdl-config: not found

If neither the .pc file not sdl-config are present, disable SDL support.
