OK for the "Manually specified Linux version", but the "Local Linux
snapshot" is expressly marked as a 2.6 snapshot:

    config BR2_KERNEL_HEADERS_SNAP
        bool "Local Linux snapshot (linux-2.6.tar.bz2)"

    [...]

    config BR2_DEFAULT_KERNEL_HEADERS
        string
        [...]
        default "2.6"       if BR2_KERNEL_HEADERS_SNAP

So, I'm not a fan of adding this for the snapshot.

I'll respin the series with jsut the manual version change. If we deem
it necessary to add it for snapshot too, this can be done in a follow-up
patch.
