    configure: Conditionalize color font feature for older freetype2
    FT_HAS_COLOR() macro is unavailable in older freetype2 without the color
    font feature.
    Compile and link a source including FT_HAS_COLOR(); if it fails (which
    can happen on older FreeType2) then define FT_HAS_COLOR(x) as (0).
