- Fixed multiple errors in "Section to Segment mapping".

- 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.

strings: fix exit status if a file before the last one fails

Previously a command like "strings f1 f2 f3" reported the exit status
based only on processing the last file.

As with GNU strings, report an error exit status if an error was
encountered processing any of the files. While here simplify the
exit status handling to just success (0) / failure (1).
