FWIW, I did volunteer to be nios2 maintainer when I submitted the port. 
 I don't know if accepting the port automatically made me maintainer, 
or not.  If there is a separate process for naming maintainers, I'd be 
fine with Chung-Lin being named a co-maintainer too since he knows as 
much about this code as I do.

Given that nios2 GCC, glibc, and Linux kernel ports are not upstream 
yet, I think "the community" is primarily using the complete toolchains 
packaged by Altera or Mentor Graphics, which already include a GDB that 
works with the other old-ABI components packaged with those toolchains. 
 Altera wants to switch completely to the new ABI, and there will be no 
old-ABI compatibility support in future versions of GCC, glibc, or 
Linux; why is it needed in GDB?
