Comment (by kencu):

 it is compiling with clang, but on 10.9 and below, it is sending the
 assembly to `as` to convert into machine code.

 the ancient `as` in `cctools` doesn't understand new-fangled assembly like
 `.subsections_via_symbols` and barfs.

 You have to force the assembly to go to llvm's integrated assembler using
 the tricks in [ticket:37846].

 At least at this moment I believe that will likely fix this. Can test
 tomorrow I think.
