Subject: Add GNU -bsd option from specs to new gnu.opt

In preparation for the driver only accepting options listed in .opt
files, and not other options that simply happen to match some spec,
this patch adds the -bsd option accepted by specs in gnu.h to a new
gnu.opt file.  (Other options are not added to this file because
<http://gcc.gnu.org/ml/gcc-patches/2011-01/msg02024.html> adds them to
gnu-user.opt, but this patch does not depend on that one; the two
patches could go in in either order.)

Tested building cc1 and xgcc for cross to i686-gnu.  OK to commit?

	* config/gnu.opt: New.
	* config.gcc (*-*-gnu*): Use gnu.opt.
