second proposed patch

The fault is 100% with ld.  GCC is producing valid dwarf2.

The *only* changes in your diff are (1) the description of the standard
opcodes, and (2) an empty line number region that has been removed.

For (1), you'll note that it *is* an extensible table.  One can add new
opcodes to the table and remain true to the dwarf2 standard.  The
consumer is free to ignore any opcodes that it doesn't understand.

I hate Apple's linker.
