Subject: Fixup SDL configure check: - Make it work without sdl-config which
 adds at least useless or even hurtful   cflags and also does not work for
 cross-compiling - If using sdl-config, make it use the CFLAGS we actually use
 for compiling   instead of something else. Thus #undef main is needed in the
 test program.
