[klibc] [PATCH/RFC] klibc/kbuild: use separate kbuild files for each klibc subdirectory
This fixes a long standing issue where it was not possible to
do "make usr/klibc/arch/x86_64/longjmp.o" in the kernel.
The principle is that all .o files to be part of klibc are listed
with klib-y. For each directory a klib.list file is made that specify
all .o file and the final AR then adds all .o files to create libc.a.
This patch introduce the infrastructure and converts x86_64 to use it.
And it breaks all other architectures...

This is as more a RFC than a real patch. It changes the kbuild part of
klibc to understand subdirectories when building the library.
My limited testing so far says that it works and it has solved
a few outstanding issues. Now for example touching SYSCALLS.def does
indeed cause a rebuild of klibc library _and_ all programs.
But it breaks all architectures in the process - but fix should be
trivial. Only that I'm too tired in my eyes to do it right away and
wanted to see if this gave some feedback from the list.
Luc van Oosten suggested the use of MRI scripts for ar but in the end
it became simpler to just use a file that listed all .o files.
Also MRI scripts was according to 'info ar' only for backward
compatibility.
Comments?
