Dwarf 2 is clearly technically superior.  Dwarf 1 has more existing
implementations, and therefore more political clout.

One important win of dwarf2 over stabs on x86 linux is that it allows for
debugging of frame-pointerless code.  In theory, that is; gdb doesn't
grok the frame unwind info yet, but all the necessary info is there.
