This is a transitional state.  Really, there isn't supposed to be a
'current' gdbarch; we're already moving away from it.

Thinking about it some more you may be right about the overall
solution though, sorry.  The target_gdbarch idea is likely to stick
around for a while.  But some work will have to be done if current and
target architectures have different register sets :-(

Isn't everything we need for this in eflags already?
