Your cross-compiler setup is incomplete. You've installed the
toolchain, but not the sysroot for the target. This ought to
include the glibc headers etc. for the target. Look into the
directory given by: arm-linux-gnueabi-gcc -print-sysroot

The kernel doesn't need any target headers, since it doesn't link
against libc.
