kbuild: sync with Linux 4.1

Update some build scripts to match Linux 4.1.  Commit-based syncing
was done so as not to break U-Boot specific changes.
The previous big sync was from Linux 3.18-rc1 by commit 176d09827725
(kbuild: sync misc scripts with Linux 3.18-rc1).

The commits imported from Linux (some with adjustments) are:
