This series is against powerpc next. The first two patches are
independent build fixes for recent patches. Patches 3-5 separate
boot Makefile BOOTCFLAGS and BOOTASFLAGS and stops passing some
C code generation flags to the assembler which causes some
warnings for llvm. Patches 6-9 are not fixes but a bunch of other
improvements I noticed along the way.

Thanks,
Nick
