IMHO is the problem in our kernel26 package. Therein we have a bad
symlink to the architecture asm directory.

[gerhard at tux1 ~]$ ls -ld /usr/src/linux-2.6.28-ARCH/include/asm
lrwxrwxrwx 1 root root 7 26. Dez 11:01 /usr/src/linux-2.6.28-ARCH/include/asm -> asm-x86
[gerhard at tux1 ~]$ ls -l /usr/src/linux-2.6.28-ARCH/include/asm/
-rw-r--r-- 1 root root 5877 26. Dez 10:43 asm-offsets.h

If compiling klibc from testing (i use 1.5.15) with the 2.6.28 patch we have
in klibc:
-----
/usr/lib/klibc/include/asm
total 8
lrwxrwxrwx 1 root root    8 2009-01-09 11:54 asm-i386 -> asm-i386
-rw-r--r-- 1 root root 5877 2009-01-09 11:53 asm-offsets.h
lrwxrwxrwx 1 root root    7 2009-01-09 11:54 asm-x86 -> asm-x86
------------
two death symlinks (asm-i386, asm-x86). These are the problems that the other
klibc-* tools don't build.

But if i change the kernel asm Symlink to:
/usr/src/linux-2.6.28-ARCH/include/asm -> /usr/src/linux-2.6.28-ARCH/arch/x86/include/asm
(for i686), then i could build
a) klibc 1.5.15 without the 2.6.28-patch
b) the other klibc-* tools from core.
