Why do you need this dependency for do_configure? Moreover, since you don't
have do_configure nor do_compile, you might want to mark them as "noexec"

How do you ensure that virtual/kernel is the TI vendor kernel? If it's not,
you'll be copying the original unmodified header into the ti/linux location.
