Does this change work with older clang and what about gcc?

Do we still use clang <3.8.0 or GCC to build kernel on HEAD? If yes then it'd be better to leave previous redefine-syms and add 3 new which will handle the translation for newer clang. I'll prepare a patch and upload tomorrow.

That will leave previous parsing intact, just add secondary options to perform proper translation on clang-3.8.0

Are there any other comments for this patch? If not, I'd like to commit it soon.

This patch is actually a workaround for an elfcopy bug that is now fixed in rS298361. It should be reverted some time later on (I will probably update the ELF Tool Chain bootstrapping test at some point).
