dmucs binary package in Ubuntu Focal arm64

 DMUCS is a system that allows a group of users to share a compilation farm.
 Each compilation request from each user will be sent to the fastest available
 machine, every time. The system has these fine qualities:
  * Works with distcc, which need not be altered in any way.
  * Supports multiple operating systems in the compilation farm.
  * Uses all processors of a multi-processor compilation host.
  * Makes best use of compilation hosts with widely differing CPU speeds.
  * Takes into account the load on a host caused by non-compilation tasks.
  * Supports the dynamic addition and removal of hosts to the compilation farm.
