I finally got around to do and test that.

That'll be my thing to decide now, after I considered your comments. ;-)
The following patch is a basis for preparing GNU Mach's build system to
have more independent stages, e.g. untangle the current Linux glue code
from the core Mach code.

This basically remains what the patch does.
I tested it both with and without enabling the kernel debugger, compiling
in all drivers that are available at the moment.
Is this ok for everyone to be applied?
2006-01-28 Thomas Schwinge <tschwinge@gnu.org>
* Makefile.in: Various cleanups. Do not include $(sysdep)/Makefrag
anymore. Move shared and system dependent stuff out of this file.
Include Makerules.
* Makerules.in: New file, mainly based on Makefile.in.
* configure.in: Check for cpp and ranlib and ar. 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. Don't build
sysdep.o, but sysdep.a. Include the top-level Makerules.
* i386/Makefrag: Removed.
* i386/Makerules: New file.
* i386/linux/Makerules: New file.
* 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.
