You should first ask yourself why <sys/reg.h> is needed in target
dependent (but host independent) code.  As I understand it,
<sys/reg.h> provides the indices by which registers may be found in
the data structures used to communicate the register's contents to/from
ptrace().  It seems to me that this information is of absolutely no
use when building a cross debugger (to x86-64), but is of vital
concern in the implementation of a native debugger.  Therefore,
<sys/reg.h> should included in the appropriate *-nat.c file instead.
