kconfig / kbuild: re-sync with Linux 4.18
Align Kconfig and Kbuild logic to Linux 4.18 release with minimal impact
on files outside of this scope.
Our previous Kconfig sync was done by commit e91610da7c8a ("kconfig:
re-sync with Linux 4.17-rc4").
A very small number of changes upstream since our sync with v4.17-rc4
that exist in the v4.18 release have already been applied here and have
been omitted from the list in this commit (and are readily available in
our own git history).
The imported Linux commits are:
