We've got a big-endian-defaulting toolchain for arm
here, but we used binutils-2.10.something and gcc
2.95.2.  So I'm not sure our patches will go in
cleanly to the tool versions you're using.  But I'll
send them along anyway; at least they'll be a decent
starting point.

Failing that, you could always just invoke little-
endian tools with -mbig-endian to gcc and -EB to gas
and gld.  That should work also.

No experience with newlib, but all a recent gdb should
need is "set endian big".  You could put that in the
project's .gdbinit once, and forget about it.  And I
think (not entirely sure) that once gdb is taken care
of, insight should be fine as well without any
additional effort.

Good luck.
