New Revision: 342918
URL: https://svnweb.freebsd.org/changeset/base/342918

Log:
  Update to ELF Tool Chain r3668
  
  Highlights:
  - Make sure that only TLS sections are sorted into TLS segment.
  - Fixed multiple errors in "Section to Segment mapping".
  - Man page updates
  - ar improvements
  - elfcopy: avoid filter_reloc uninitialized variable for rela
  - elfcopy: avoid stripping relocations from static binaries
  - readelf: avoid printing directory in front of absolute path
  - readelf: add NT_FREEBSD_FEATURE_CTL FreeBSD note type
  - test improvements
  
  NOTES:
  
  Some of these changes originated in FreeBSD and simply reduce diffs
  between contrib and vendor.
  
  ELF Tool Chain ar is not (currently) used in FreeBSD, and there are
  improvements in both FreeBSD and ELF Tool Chain ar that are not in
  the other.
