I've noticed this in antioxidant (and fixed it there locally) but didn't 
report it yet.

Anyway, this can be done more simple -- all that I needed to do was 
deleting the freetype2 subdirectory (in a snippet) and adding 'freetype' 
to inputs.  Patching the build script or build.rs was not necessary.

Additionally, I noticed that in the modified build.rs, only 
rustc-link-lib (-l) is set, but not rustc-link-search (-L). Antioxidant 
needs the latter to be set, otherwise dependents will fail to link 
because of not finding the freetype library.

Greetings,
Maxime.
