Subject: [PATCH] Evas: fine tuned the harfbuzz checks to make sure harfbuzz
 was compiled with freetype support and just check if it also compiled with
 glib support. ATM there's no good lib for checking unicode characteristics so
 until there is one, we optionally use harfbuzz's glib integration - such lib
 is planned by the guy who wrote Harfbuzz.
