Pull objtool fixes from Borislav Petkov:

 - Adjust objtool to handle a recent binutils change to not generate
   unused symbols anymore.

 - Revert the fail-the-build-on-fatal-errors objtool strategy for now
   due to the ever-increasing matrix of supported toolchains/plugins and
   them causing too many such fatal errors currently.

 - Do not add empty symbols to objdump's rbtree to accommodate clang
   removing section symbols.
