	Clean up linux emulation code to make it architecture-independent
	as much as possible.

	* linux: Renamed from linuxdev.
	* Makefile.in (objfiles): Add linux.o instead of linuxdev.o.
	(MAKE): New variable. Used for the linux.o target.
	* configure.in: Add AC_CHECK_TOOL(MAKE, make).
	* i386/i386/spl.h: Include <i386/ipl.h>, for compatibility with
	OSF Mach 3.0. Suggested by Elgin Lee <ehl@funghi.com>.
	* linux/src: Renamed from linux/linux.
	* linux/dev: Renamed from linux/mach.
	* linux/Drivers.in (AC_INIT): Use dev/include/linux/autoconf.h,
	instead of mach/include/linux/autoconf.h.
	* Makefile.in (all): Target ../linux.o instead of ../linuxdev.o.
	* linux/dev/drivers/block/genhd.c: Include <machine/spl.h> instead
	of <i386/ipl.h>.
	* linux/dev/drivers/net/auto_irq.c: Remove unneeded header files,
	<i386/ipl.h> and <i386/pic.h>.
	* linux/dev/init/main.c: Many i386-dependent codes moved to ...
	* linux/dev/arch/i386/irq.c: ... here.
	* linux/dev/arch/i386/setup.c: New file.
	* linux/dev/arch/i386/linux_emul.h: Likewise.
	* linux/dev/arch/i386/glue/timer.c: Merged into sched.c.
	* linux/dev/arch/i386/glue/sched.c: Include <machine/spl.h> instead
	of <i386/ipl.h>, and moved to ...
	* linux/dev/kernel/sched.c: ... here.
	* linux/dev/arch/i386/glue/block.c: Include <machine/spl.h> and
	<linux_emul.h>, instead of i386-dependent header files, and
	moved to ...
	* linux/dev/glue/blocl.c: ... here.
	* linux/dev/arch/i386/glue/net.c: Include <machine/spl.h> and
	<linux_emul.h>, instead of i386-dependent header files, and
	moved to ...
	* linux/dev/glue/net.c: ... here.
	* linux/dev/arch/i386/glue/misc.c: Remove `x86' and moved to ...
	* linux/dev/glue/misc.c: ... here.
	* linux/dev/arch/i386/glue/kmem.c: Moved to ...
	* linux/dev/glue/kmem.c: ... here.
