I see libexecdir CAN be changed.. so the above is already possible..

The part they had hard coded is "/usr/lib/ConsoleKit"...  There is only one
location in the system for ConsoleKit configuration files/scripts.. and that is
distro specific.  Assuming the oe based distributions use
$(PREFIX)/lib/ConsoleKit.. then the previous was correct.

The point being it doesn't matter if it's 32-bit, 64-bit or 24-bit...  only one
ConsoleKit per system should exist.  (There are potentially other files on the
system like this.  I know a recent RPM patch went in that separated /usr/lib/rpm
and /usr/lib64/rpm..  this is also a similar mistake, I just haven't had time to
get a patch out to revert that chunk.)
