[Buildroot] [PATCH 6/7] linux: do not check hashes for custom versions and tarballs

 Hah, this is a tough one...

 With the combination BR2_LINUX_SAME_AS_HEADERS and BR2_KERNEL_HEADERS_VERSION
you can still get a custom version...

 So I'm thinking if it wouldn't be simpler to just always disable the hash:
BR_NO_CHECK_HASH_FOR += $(LINUX_SOURCE)

 Note that the hash, if it exists, will still be checked; it just won't be an
error if the hash doesn't exist (so the variable is not named very accurately in
fact). Therefore I think it's safe to disable it completely for linux. Or, if
you prefer you can make it depend on !BR2_LINUX_KERNEL_LATEST_VERSION &&
!(BR2_LINUX_SAME_AS_HEADERS && !BR2_KERNEL_HEADERS_VERSION) (good luck
expressing that in make syntax :-).

 Why do you add that comment here and not in the VCS cases? I don't think it is
needed, move it to the commit message.
