This patch contains changes to the libSDL port that were needed to build the Hatari emulator using cmake. - Since SDL programs cannot use the posix library (because sdl's init function needs a way to get hold of the Genode env), the sdl_main library must be used instead of the posix library. The sdl_main code implements the Libc::Component::construct function for the final binary. However, 3rd-party build systems are not aware of this Genode-specific peculiarity and thereby create binaries that leave libsdl uninitialized. This patch adds the sdl_main to libsdl by default and thereby eliminates the need for specifying the extra sdl_main library. Customizing the Libc::Component::construct is still possible by overriding the library-provided implementation in the main program. - A few missing config definitions are added to compile Hatari successfully. - Avoid reliance on the include/SDL convention in SDL_config.h - Cmake relies on the upper-case naming of the library with no way to tweak this convention. So we install an symlink named `SDL.lib.so` when installing the library into the <build-dir>/bin/ directory. Fixes #161
