[Buildroot] [PATCH] ghostscript: not compiled to use freetype lib

[Thomas Ehrhardt <tehrhardt@innovaphone.com>]

Hi Thomas,

the ghostscript isn't compiled against the freetype lib although it is
switched on. Ghostscript doesn't support cross compiling and the old
freetype sources within ghostscript are deleted. So the headers of the
freetype package must be included, and the ghostscript configure is changed
to use the host pkgconfig.
