[PATCH v2 0/6] Fixes for new mach-o load commands

[Roman Bolshakov <r dot bolshakov at yadro dot com>]

Hello dear maintainers,

Apple has added a set of new load commands that weren't handled by bfd.
Some of them are rarely processed by binutils, like binaries with
LC_VERSION_MIN_TVOS.

But inability to handle LC_BUILD_VERSION resulted in a few bug reports,
and rendered binutils/gdb to be unusable with Mojave binaries:
  binutils/23728, gdb/23742, binutils/23746

The patch series implements processing of the new commands in bfd and
dump routines in objectdump.

I'm leaving the original cover message as is because couple hours after
v1 patchset, another commit came into master brach that fixes the
aforementioned errors on macOS Mojave by skipping LC_BUILD_VERSION
command.

The patchset should still be helpful as it does parse LC_BUILD_VERSION
and a few other load commands.
