[task #5956 --- ``Automake'ify GNU Mach's code base'']

	* Makefile.am: New file.
	* Makerules.am <configure's findings, System dependent Makerules>
	<Compilation flags, Dependency generation, Autoconf support>: Remove
	sections.
	<Building from foo.cli, Building from foo.srv>: Rewrite:
	(%.server.defs.c, %.user.defs.c, %.server.h %.server.c)
	(%.user.h %.user.c, %.server.defs, %.user.defs): New targets.
	(%.h %_user.c %.cli.d, %_interface.h %_server.c %.srv.d): Remove
	targets.
	(echo-%): New target.
	* Makefrag.am <configure's findings, Rules, Kernel Image, Installation>
	<Building the distribution, Autoconf support, Makerules>: Remove
	sections.
	(enable_kdb, enable_kmsg): Adopt.
	<All the source in each directory>
	<Header files installed for user use>: Rewrite to adopt to how things
	are to be done now.
	<Automatically generated source files>: New section.
	(i386/Makefrag.am): Include file if appropriate.
	* i386/Makefrag.am <configure's findings, Rules, Installation>
	<Autoconf support, Makerules>: Remove sections.
	(enable_lpr): Adopt.
	<Source files for any i386 kernel>: Rewrite to adopt to how things are
	to be done now.
	* i386/linux/Makefrag.am: New file.
	* linux/Makefrag.am: Likewise.
