# Trick to make this build on nix. It expects to have the kernel sources
# instead of only the linux kernel headers.
# So it cannot run the 'make headers_install' it wants to run.
# We don't install the headers, so klibc will not be useful as libc, but
# usually in nixpkgs we only use the userspace tools comming with klibc.
