In general, I think a PTRACE_GET/SETREGS interface is be more robust
than groveling around the u. struct.  If the register struct changes,
both methods fail.  But if the u. struct is changed for an unrelated
reason, GET/SETREGS may continue to work.

If this is true for Linux, perhaps this is a case GDB can influence
those Linux ports that don't currently implement GET/SETREGS.  If
possible, I think we should try to fix problems rather than working
around them.
