Create initial kernel ABI header infrastructure
The model proposed for the new kernel ABI headers is that the headers
pertinent to both kernelspace and userspace would be reorganized and
cleaned out into include/kabi. The new headers should stay in a restricted
namespace such that they are useable anywhere. Just as include/asm is
symlinked to include/asm-$ARCH, include/kabi/arch will be symlinked to
include/kabi/arch-$ARCH to provide a straightforward way of selecting the
correct architecture ABI.
This creates the first architecture-specific header file, "stddef.h", which
implements a basic BITS_PER_LONG definition, and adds the corresponding
Makefile bits to create the include/kabi/arch symlink.
There's probably something else that needs to be done about getting the
correct include/kabi/* files in the tarball but I'm not aware of it at this
time, so I'll just pretend it doesn't exist :-D.
This appears to compile correctly with allmodconfig on powerpc (32-bit)
