Well, I agree, not necessarily needed, but would be nice to be clean.
The config check will be probably the only way I see. Means freetype2 
version < 2.2.0 _no_ const qualifiers, freetype2 version >= 2.2.0 use const.

But, my freetype2 version shows 9.7.3 :( from X.org......

Have to think about it then.
