The last target that used core-regset.c (FreeBSD/alpha) has been
removed with GDB 8.0, and since then this file is obsolete.

are used in the interaction with /proc (Irix 4 is an exception and
therefore doesn't use this file). Quite a few systems without a
SVR4-ish /proc define these structures too, and can make use of
this code too. */
