[Skiboot] [PATCH v2 00/11] Support building with clang

[Joel Stanley]

Hello Skibooters!

This series contains cleanups and modifications that are required to
build skiboot with clang. This is version 2. It reorders the makefile
changes, drops some patches for the r13 handling (we didn't need them!)
and improves the parity() patch.

If you want to try it out:

 $ sudo apt-get install clang
 $ make CC=clang

I've done all of my testing with clang-7 (trunk). Clang 6 works fine
