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.

d133198b4b libdwarf: Handle .rel relocations
Some architectures use .rel relocations (for debug data), so they must
be handled.

This was discovered from ctfconvert on ARM object files.  The lack of
relocation handling caused all string lookups to return the string at
offset 0 in .debug_str, typically "FreeBSD clang version ..."
