Xcode DWARF-in-objects support

The binary has no DWARF, but has a bunch of links to .o files in symtab/linkedit, you are expected to follow them and effectively perform linker's job. What's the symtab like? dsymutil --symtab dumps it. https://github.com/llvm-mirror/llvm/blob/master/tools/dsymutil/dsymutil.cpp
