b6b6f9cc7c Update to ELF Tool Chain r3475
Improvements include:

 * Add support for reporting and handling a number of new constants in
   various tools, including:
    * CloudABI OSABI
    * DT_TLSDESC_*
    * i386, MIPS, SPARC and amd64 relocations

 * C++ demangler bug fixes

 * Man page updates

 * Improved input validation in several tools

This update also reduces diffs against upstream as a number of fixes
included in upstream were previously cherry-picked into FreeBSD.

71a0c925ce Update elftoolchain to upstream revision 3163
Most of our changes have now been committed upstream, so this change is
largely bookkeeping.

ccbdcd03f2 libelf: Fix cross-endian ELF note file / memory conversion
The namesz and descsz variables need to be used in native endianness.
The sizes are in native order after swapping in the file to memory case,
and before swapping in the memory to file case.

This issue was identified for r273443, but the change was applied to the
wrong case. Revert r273443 to fix the to-memory case, and apply the
equivalent change to the to-file case.

c10185837c Fix the conversion macro for .note sections, broken in the case
the ELF file's byte order is not the native byte order.  The
bug is that the variables holding the name and description size
are used (natively) after having been byte-swapped.  The fix is
to calculate sz from them just prior to byte-swapping.
