Take a look at e.g. mipsnbsd-nat.c and mipsnbsd-tdep.c (I'm slowly
making all NetBSD configurations fully cross-debug'able, and MIPS
and SH are good examples of my strategy).

As far as I'm concerned, it's simply not appropriate to be using generic
"regset" routines, because the names of those routines inherently make
them impossible to use for cross-debugging, especially in a truly multi-arch
environment (or even one as simple as "32-bit code running on x86-64").
