This patch enhances the algorithm which finds the correct settings for SDL. For cross compilations (when cross_prefix is set), it looks for sdl-config with cross prefix. Here is the complete search order:
$(cross_prefix}pkg-config (old, only used for cross compilation) ${cross_prefix}sdl_config (new, only used for cross compilation) pkg-config (old, needs PATH) sdl-config (old, needs PATH) Cross SDL packages (or the user) now can simply set a link (for example /usr/bin/i586-mingw32msvc-sdl-config -> /usr/i586-mingw32msvc/bin/sdl-config) which allows cross compilations without PATH modifications. Without the patch, configure and make (which calls configure) typically need a non-standard PATH. Failing to set this special PATH results in broken builds. v2: * Favour pkg-config over sdl-config for cross compilations (suggested by Aurelien Jarno) and add comment for this.
