The necessary hooks were already present in i386bsd.c, but I didn't
check in the necessary configure support for the %fs and %gs
registers.  I checked it in now.

	* acconfig.h (HAVE_R_FS, HAVE_R_GS): Add.
	* configure.in: Add checks for r_fs and r_gs members of
	`struct reg'.
	* config.in, configure: Regenerated.
