Solution A is problematic because it then would require to install
headers into ${WORLDTMP}. This is what buildworld does.
Solution B is problematic because arm_neon.h uses stdint.h types
extensively.
Maybe the solution with the least amount of work is to provide a
kernel-specific wrapper header with the stdint.h types.
Otherwise, just use buildworld before buildkernel.
