After reverting some changes in libfreetype 2.1.10 (see patch
attached) the Xserver no longer crashes on x86_64, so it must have
been the same problem as on i386 since there are no other references
for find_sbit_image/load_sbit_metrics in the Freetype module
sources. Since I'm quite sure, that these changes were intentional the
libfreetype patch should only be used as workaround for now. The
libfreetype developers didn't comment yet.
