I did some work on integrating klibc into kbuild now. I used your patch as
guide line, though I started from scratch with klibc-0.77. The build
should work fine (reminder: "make KBUILD_VERBOSE=0 ..." will give you much
more readable output), but I probably broke some non-x86 architectures
in the process.

To do something more useful than "hello world", I actually moved some part
of finding / mounting the final root system into userspace, though only
conditional on CONFIG_INITRAMFS.

My tree is at

Pull from http://linux-isdn.bkbits.net/linux-2.5.klibc

If people want a GNU patch, I can mail that privately, it was too large to
attach it here.

kbuild/klibc: Integrate klibc into the build.
Basically, add a scripts/Makefile.user, which does similar things to
scripts/Makefile.build, but compiles userspace for the target instead.

It's tested for a static klibc on i386, building the shared lib works, too,
but is not further integrated.

This patch also adds gregkh's hello test program, which works as well.

Greg's fix used fwrite on a file descriptor obtained from open(), which
only works by luck, since for klibc FILE * == fd.

Use standard C lib functions for open/close.

klibc: gen_init_cpio file generation fix
I found what kept initramfs from working here: While creating

unpacking the archive by hand.

klibc: Stop on error when building the CPIO
gen_init_cpio still referenced hello in usr/hello_world, but I put it
into usr/root. This is now corrected, however it also pointed out the
common problem that the error code of gen_init_cpio is ignored since
it's output is piped to gzip. To fix that, make the generation of the
.cpio.gz a two step process.

klibc: Move mounting of the root filesystem into userspace
When selecting CONFIG_INITRAMFS, init/do_mounts.c is not compiled anymore,
and it's task is taken over by a small /sbin/init running in initramfs.

However, this is a proof of concept only, the userspace code only handles
mounting a local filesystem, no support for nfs / initrd / devfs yet.
