New Revision: 249059
URL: http://svnweb.freebsd.org/changeset/base/249059

Log:
  MFC r248802:
  
  Similar to r239870 and r239872, teach the other binutils tools about the
  DW_FORM_flag_present dwarf attribute, so they do not print errors or
  warnings on files that contain it.  (This attribute can be emitted by
  newer versions of clang and gcc.)
