Regarding CONFIG_* options, I would expect most of the configuration

Sami, I don't think it's fair to ask you to support both Clang and GCC in
your patchset, but, where changes are obviously toolchain-agnostic, could
you use CONFIG_LTO?  And use CONFIG_LTO_CLANG for Clang-specific parts?

Sure, using CONFIG_LTO for common code and CONFIG_LTO_CLANG for clang-
specific parts sounds good.
