Author: kaiw

New Revision: 260991
URL: http://svnweb.freebsd.org/changeset/base/260991

Log:
  Reapply revisions r237528, r237531 and r238741 which make libelf
  properly include sys/ headers from the source tree instead of the
  host.
  
  These patches are also applied to libdwarf since libdwarf requires
  the same sys/ headers as libelf.
