New Revision: 448576
URL: https://svnweb.freebsd.org/changeset/ports/448576

Log:
  Add LLD_UNSAFE to force use of ld.bfd when ld is lld
  
  By default the compiler will find /usr/bin/ld for the linker.  If a port
  sets LLD_UNSAFE and /usr/bin/ld is ld.lld, then add -fuse-ld=bfd to
  force the use of the binutils BFD linker (from the base system, if
  available, or by setting USE_BINUTILS).
  
  This change is based on an earlier, similar patch from bapt, with the
  addition of the -fuse-ld flag.
