Description: Fix ac_find_xft.m4
 ac_find_xft.m4 fails tests required to enable building with Xft anti-aliased fonts.
 We also need to add -lfontconfig to LIBS to prevent underlinking of libXm.
 .
 This patch fixes these.  Build-depends on libfontconfig1-dev, libfreetype6-dev and
 libxrender-dev can be dropped as they are all dependencies of libxft-dev.
