Cleanup of GNU Mach's build system.  The system dependend parts are now
	handeled by the respective Makefile and no longer by the top-level one.

	* configure, i386/configure, i386/linux/configure, linux/configure:
	Regenerated.

	* Makefile.in: Various cleanups.
	(mach/machine, mach_machine): Targets removed.
	(AWK, CC, CFLAGS, CPPFLAGS, DEFINES, INCLUDES, INSTALL, INSTALL_DATA)
	(INSTALL_PROGRAM, LD, MIG, MIGFLAGS, NM): Variables moved into
	Makerules.in.
	Do not include $(sysdep)/Makefrag anymore.
	(all, check, clean, distclean, mostlyclean, maintainer-clean, install)
	(install-headers, install-kernel): Recurse into the system dependend
	subdirectory.
	(check): Add a basic test using mbchk.
	(clean, distclean): Be more explicit in what to delete.
	($(systype)/%): New target.
	(kernel.o): Incorporate the system dependend archive.
	(installed-sysdep-headers-names, $(installed-sysdep-headers-names)):
	Variable and target moved into the system dependend Makefile.in.
	(install-headers, mkheaderdirs): Don't care for the system dependend
	header files.
	(%.symc, %.symc.o, %.h, %_user.c, %_interface.h, %_server.c): Targets
	moved into Makerules.in.
	Inclusion of dependency files: Likewise.
	(%.migs_d, %.migu_d, %.migsh_d, %.miguh_d, make-deps, %.d): Likewise.
	Include Makerules.
	* Makerules.in: New file, mainly based on Makefile.in.
	* configure.in: Do not substitute cross_compiling and not explicitly
	substitute LDFLAGS.
	Check for cpp, ranlib, ar and mbchk.
	Care for the mach/machine symbolic link.
	Add Makerules as a config file.
	* i386/Makefile.in: Various cleanups.
	Merge i386/Makefrag and the system dependent stuff from Makefile.in
	into this file.
	(all, check, install, install-headers, install-kernel): Recurse into
	the system dependend subdirectory.
	(sysdep.o): transformed to the new target sysdep.a.
	(linux/linux.o): Target removed.
	(clean, distclean): Be more explicit in what to delete.
	(linux/%): New target.
	(install-headers): Install the system dependend header files.
	(mkheaderdirs): New target.
	Include the top-level Makerules.
	* i386/Makefrag: File removed.
	* i386/Makerules.in: New file.
	* i386/configure.in: Synchronize AC_INIT to the top-level definition.
	Do not check for ld and make.
	Add Makerules as a config file.
	* i386/linux/Makefile.in: Various cleanups.
	Replace linux-objs with objfiles.
	(check, install, install-headers, install-kernel): New empty targets.
	Don't care about linux-flags if no_deps is true.
	Inclusion of dependency files removed and instead...
	Include the top-level Makerules.
	* i386/linux/Makerules.in: New file.
	* i386/linux/configure.ac: Synchronize AC_INIT to the top-level
	definition.
	Do not check for gcc and ld.
	Do not explicitly substitute LDFLAGS.
	Add Makerules as a config file.
	* linux/configure.in: Synchronize AC_INIT to the top-level definition.
	Do not create directories using a dummy file.
	* linux/dummy.in: File removed.

	* ddb/db_access.h: Include <machine/vm_param.h> instead of
	"vm_param.h".
	* kern/bootstrap.c: Likewise.
	* kern/thread.c: Likewise.
	* vm/vm_kern.c: Likewise.
	* vm/vm_object.c: Likewise.
	* vm/vm_resident.c: Likewise.
