into ports.
Me and Niclas plan to meet up and get this committed when I'm in Stockholm

Other info
-------------

>From Jan Beich on mailing list rather important info:
"libEGL requires devel/llvm40 which isn't supported on some platforms[1],
mainly sparc64. If WAYLAND is added to OPTIONS_DEFAULT make sure to also
add OPTIONS_EXCLUDE_sparc64=WAYLAND."
