The status of that port is somewhat unclear.
Although the files state they are copyrighted Red Hat, I believe that
is wrong. They might be derived from some other backend which was. But
I think the original authors have disappeared.
The other problem has been that we don't seem to have anybody with MIPS
experience/setups that can help test/integrate the port.
Also, in the past the port made changes to the generic libelf code that
caused bugs on other architectures:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=794488
Which made me somewhat suspicious about this backend.
Best would be to discuss with the Debian maintainer, Kurt Roeckx <
kurt@roeckx.be>, how to move this forward/upstream.
Thanks,
Mark
