That's a weird Ubuntu (or Debian?) quirk. It shouldn't be necessary
but it probably shouldn't be fiddled with either, except maybe to
'chmod -h o-w /usr/bin/X11' (to remove the world-writable permission
from the symlink.)
it's for backward compatibility, some programs used to search for X binaries
in /usr/bin/X11/, but since they are stored in /usr/bin, X11 symlink was
created to point to current directory (thus, /usr/bin).
the symlink permissions are not important, from chmod man page:
chmod never changes the permissions of symbolic links; the chmod system
call cannot change their permissions. This is not a problem since the
permissions of symbolic links are never used.
