This doesn't seem to be possible. Debian doesn't provide mips64 packages <br>
for big-endian[!] mips. I apologize for the distraction. On related <br>
note, they seem to have removed big-endian mips from their dist mirrors <br>
altogether, one has to pull them from <a href="http://archive.debian.org" rel="noreferrer" target="_blank">archive.debian.org</a>.<br>

<br>
The point is that gdb with multiarch allows you to remotely debug <br>
multiple "alien" architectures and it should handle multiple ABIs on the <br>
same machine. If the package doesn't work, then one would have to either <br>
figure out how to make the multiarch config work, or venture to compile <br>
a 64-bit debugger with corresponding dependencies. Debian has given up <br>
on big-endian mips.<br>
