bfd Mach-O DWARF debugging support


Hi,

I was wondering about the current state of the Mach-O DWARF debugging
support. I saw some patches recently which implemented
`bfd_mach_o_find_nearest_line` (that is mostly what I am interested
in).

I have a binary which was build via `gcc -gdwarf-2` (Apples GCC).

I tried binutils-2.22.52 but it doesn't really work for me. I tried to
debug it a bit. Some things I can say so far:

* `objdump -g` doesn't output anything regarding debugging info.
* In bfd/dwarf2.c, in find_line(), _bfd_dwarf2_slurp_debug_info returns false.
* In _bfd_dwarf2_slurp_debug_info(), find_debug_info returns false.
* `objdump -h` doesn't list any debug section.

When I use `dsymutil` to generate a dSYM from my binary,
`bfd_mach_o_find_nearest_line` works.

Can somebody give some hints wether it should work or about the current state?

Regards,
Albert
