libsdl2-ttf: Check for x11 and opengl in distro features

when X11 is not in distro features it tries to link with
libGL which does not exist and compile fails

Add a patch to add foreign option to AUTOMAKE_OPTIONS
which lets it configure and relax automake rules to not
check for some GNU specific files
