[FFmpeg-cvslog] configure: Special case libfreetype test

[Alexander Strasser]

ffmpeg | branch: release/1.2 | Alexander Strasser <eclipse7 at gmx.net> | Fri Dec  6 17:20:26 2013 +0100| [dcd1acce1a69aebc36306a1155c025cc4175badc] | committer: Alexander Strasser

configure: Special case libfreetype test

Include the freetype header, in-directly through a macro, like it
is done in the drawtext filter. Do not break if the header is moved.

Unfortunately the drawtext filter included the file where the include
macros are defined in a wrong way. This is not needed and breaks the
build. Remove that #include line too.

(cherry picked from commit cea5812fa723c08b89d929eeba73462e05de2973)
