The simplest method was to add an extra asm-offsets.h
file in arch/$ARCH/include/asm that references the generated file.

We can now migrate the architectures one-by-one to reference
the generated file direct - and when done we can delete the
temporary arch/$ARCH/include/asm/asm-offsets.h file.

Adjust the asm symlink support so we do not create the
symlink unless really needed.
We check the precense of include/asm-$ARCH by checking
for the system.h file. We may end up with a stale directory
so it is not enough to check if the directory is present.

Since 97965478a66fbdf0f4ad5e4ecc4828f0cb548a45 ("mm: Get rid of __ZONE_COUNT")
mmzone.h includes bounds.h.
Calling make clean after make prepare removes bounds.h
again so when building external modules this fails.

Add the ability to pass comments into asm-offsets.h by generating asm
output like

-># comment line

Mips needs this feature to preserve the comments that are in
asm-mips/asm-offsets.h right now.

Then remove the special handling for mips from Kbuild and convert mips to use
the new string to include the comments.

The use of enums create constants that are not available to the preprocessor
when building the kernel (f.e.  MAX_NR_ZONES).

Arch code already has a way to export constants calculated to the preprocessor
through the asm-offsets.c file.  Generate something similar for the core
kernel through kbuild.

Preparatory patch for the source merge of arch/i386 and arch/x86_64
into arch/x86. This allows to keep the original arch directories as
stubs for the main Makefiles, Kconfigs et. al during the transition
phase while having the code in the new arch/x86 directory.

Most system calls seems to get added to i386 first. This patch
automatically generates a warning for any new system call which is
implemented on i386 but not the architecture currently being compiled.
On PowerPC at the moment, for example, it results in these warnings:
init/missing_syscalls.h:935:3: warning: #warning syscall sync_file_range not implemented
init/missing_syscalls.h:947:3: warning: #warning syscall getcpu not implemented
init/missing_syscalls.h:950:3: warning: #warning syscall epoll_pwait not implemented

The file scripts/checksyscalls.sh list a number of legacy system calls
that are ignored because they only makes sense on i386 systems.
