[PATCH 1/1] Adjust fallback definition of DBREG_DRX for netbsd


This was originally inteded for freebsd~=5. freebsd has since moved
to the definition here, including the rename dr0->dr.

netbsd now uses the same definitions as freebsd, including the use
of dr instead of dr0, but doesn't provide this macro.
