He's on GNU/Linux, IIRC...
Doing cross coredumps is trivial; I put all the BFD machinery in place
for a number of GNU/Linux targets, and others did it for the various
BSDs. I'd post my ARM patches for this but I doubt even a line of them
applies any more after your extensive ARM cleanups.
The only thing you have to do is move supply_gregset and
supply_fpregset to the tdep file, and then link in corelow/core-regset
as target instead of nat objects. This means a little bit of grubbing
about in target header files to copy out definitions for regsets, but
only a little.
