    M lld/test/MachO/search-paths.test
    A lld/test/MachO/syslibroot.test

  Log Message:
  -----------
  MachO: support `-syslibroot`

This adds support for the `-syslibroot` option.  This is required to
make the library search order actually function.  With this, it is now
possible to link a test Darwin x86_64 program with lld on Darwin.
