Your toolchain can't find your headers.

I've built a root filesystem for arm, and I've done so building my own
cross compiler from source, and using busybox as the basis for the
development environment.

The build is just a series of bash scripts, which are at:

  http://landley.net/aboriginal

There's prebuilt binary versions of everything there (cross compiler,
native compiler, root filesystem tarball suitable for chroot, filesystem
and kernel packaged to boot under qemu...)

And there's a really big long explanation of what it's doing at:
