[PATCH, RFC] Add linux-libc-headers-native, make it default dep for native

[Tom Rini <tom_rini@mentor.com>]

On some host distributions the provided linux kernel headers are too old
to compile utilities we need[1].  Given that we need these utilities to
run things on the target the best solution is to provide
linux-libc-headers-native.  Rather than get things into an inconsistent
state, we make linux-libc-headers-native be a default dependency.

[1]: A prime example of this would be mtd-utils-native and UBI
