fwiw - I updated the patch to use different names on different archs,
can you guys review?
case llvm::Triple::x86:
case llvm::Triple::x86_64:
return ".mcount";
case llvm::Triple::mips:
case llvm::Triple::mipsel:
case llvm::Triple::ppc:
case llvm::Triple::ppc64:
return "_mcount";
case llvm::Triple::arm:
return "__mcount";
