PATCH: more cross cores

This just fills in cross core support for some other Linux targets the same
way that I implemented it for MIPS/Linux; nothing surprising. I think that
when I have a little spare time I will try to redo this in a way that
involves less code duplication, but it's fine the way it is - and BFD has
larger issues of code duplication to shoot, anyway.
All the affected targets have been built, and the cores checked with a
patched cross-gdb.
OK to commit?
