If you could give me a link to your previous mail having the guidance steps, that would
be helpful.

The sketchy directions I gave were for supporting an architecture as is
done today, i.e., such that the host machine type would run its arch-specific
crash utility binary.
The only "cross-arch" support is the x86_64's capability of running a
32-bit
x86 binary. (and perhaps the same can be done on an ia64). But to run an
x86 binary to view an ARM dumpfile would be yet another level of complexity
for which there's no support.
There is a "cross-crash" utility maintained elsewhere -- I don't know
where or not it's still active -- and which if I'm not mistaken, supports
running an x86 crash binary to look at a MIPS vmcore. There also was
a group doing the same kind of thing for using an x86 binary to look
at 32-bit ppc vmcores. But again, I have no details on either initiative.
