+Subject: build: Use pkg-config to find FreeType
+
+pkg-config is apparently preferred over freetype-config these days (see
+the BUGS section of freetype-config(1)). pkg-config support was added
+to FreeType in version 2.1.5, which was released in 2003, so it should
+comfortably be available everywhere by now.
+
+We no longer need to explicitly substitute FREETYPE_CFLAGS and
+FREETYPE_LIBS, since PKG_CHECK_MODULES does that automatically.
+
+Fixes Debian bug #887721.
