Other (better?) solution without the need to modify kernel26:
Copy the needed asm Include files and directories to klibc/klcc's
include dir. I attach a modified PKGBUILD for klibc (upstream version
1.5.15).
This is quick&dirty, but it works. For klibc itself the 2.6.28.patch is
still needed but the other klibc-* tools build without errors.
BTW: about the two death symlinks: these are also in current core klibc
package. The i386 symlink is produced by klibc make itself, the other
(asm-x86) by our PKGBUILD.
For ext4 support the patch is no longer needed.

I tested on i686.
