gd 2.0.33: Explicitly disable support for freetype and fontconfig. There are
two issues if this isn't done:
- If you have these built under OE then support for them will be included,
  otherwise it won't be. Explicitly disabling these ensures support is never
  included.
- If you don't have these built under OE it will attempt to use the host
  versions of these libraries. (Picked up be insane.bbclass).
