ae500c1ff8 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.

2ef476c9a2 Follow DW_AT_specification when looking up DW_AT_type attributes.
dwarf_attrval_*() will search the parent DIE referenced by a
DW_AT_abstract_origin attribute for the value of the DW_AT_type attribute.
Do the same thing for the DW_AT_specification attributes in variable
definitions emitted by GCC 6.2, and ensure that we return an error rather
than crashing if neither DW_AT_abstract_origin or DW_AT_specification is
found when looking for the value of the DW_AT_type attribute.

9c016dc4b2 API dwarf_attrval_flag() should properly handle an attribute with
(DWARF4) form DW_FORM_flag_present which implicitly indicates the
presence of the attribute. Manual page is updated to reflect this
change.

Note that this was previously fixed in the old libdwarf.
