Log:
  devel/libunwind: set LLD_UNSAFE
  
  libunwind.so has symbols with ELF protected visibility which various
  test applications could preempt. Both GNU gold and LLVM's lld fail to
  link this case, with errors like
  
  lld:
  /usr/bin/ld: error: cannot preempt symbol: _ULx86_64_init_local
  >>> defined in ../src/.libs/libunwind.so
  >>> referenced by Lperf-trace.c
  >>>               Lperf-trace.o:(main)
  
  gold:
  /usr/local/bin/ld.gold: error: Gperf-simple.o: cannot make copy relocation
      for protected symbol '_Ux86_64_local_addr_space', defined in
      ../src/.libs/libunwind-x86_64.so
  
  For now prevent libunwind from linking with lld. More information can be
  found in libunwind upstream issue 58
