Log:
  Fixup build with llvm/clang:
  
  https://reviews.llvm.org/D23497 and the attached FreeBSD patch work together
  to fix this problem and should be sufficient so long as you don't have
  -save-temps or -via-file-asm in your compiler flags. The LLVM patch makes the
  .local directive work properly when assembling an ELF while the FreeBSD patch
  ensures the assembler never sees a forward-declared local label by declaring
  them in advance with .local. However, the LLVM patch currently breaks if you
  use -save-temps or -via-file-asm since MCAsmStreamer's implementation of .local
  doesn't do anything to the MCSymbol and only emits a .local directive. This
  causes the assembler to interpret it as an external symbol and emit the wrong
  jal expansion.
