head -r309179 clang 3.9.0 TARGET_ARCH=powerpc64 cross-built buildkernel stops for: rejected assembler notation

[Mark Millard]

[To get this far I had to use WERROR= to get past other C/C++ rejections.]

Below are some example errors that clang 3.9.0 reports for trying to
handle the assembler notations that are used:
