Some other interfaces are set in stone. I think the BFD interface is
pretty much the exact opposite, whatever that is.

There is a certain degree of overlap with objdump --debugging.
However, that gives you more than you need, and the format is not
really what you are looking for. I wonder if it would make sense to
modify the debug readers used by objdump --debugging to have a mode in
which they just return line number information. Of course, somebody
would have to implement a DWARF debugging reader to make this useful
in the current normal case.
