Thanks for the report, should now be fixed. This also uncovered another issue, that cxxfilt should be in the toolchain package not clang, which will get fixed in a later change.

Add a new Makefile under clang/toolchain to create the symlinks and man links for ar, c++filt, nm, and so on (without the llvm-* prefix) when LLVM_BINUTILS is enabled (as it is by default).
