linux-headers: Improve derivation, removing cross arg - Perl is used at build time, so must be in `nativeBuildInputs`. It's not used at run time so it should not be in `buildInputs`, too. - Don't treat headers like a compiler---use the build and host platforms not host and target. Perhaps that would make sense if every library's headers could be a separate derivation, but since that is not feasible, best to keep the implementation and interface in the same stage. To do this, we used `stdenvNoCC` to get rid of the normal toolchain, and added a dependency for the toolchain targeting the build platform --- `buildPackages.stdenv.cc` --- thus everything is effectively slid a stage black.

linux-headers 4.4: Remove arch fallback code @dezgeg was right: The `platform` field of a linux platorm is already manadatory---if not specified it is inferred, and all such inferences include a `kernelArch` field. Therefore linux packages can indeed rely on it being defined.
