[addr2line] Printing symbol names

[Jiří Wolker]

Hello,

I can't find a way to print symbol names for non-functions using
‘addr2line’. It is possible to print function names, but this prints
just ‘??’ for symbols in data sections.

I did not notice any option relevant to printing symbol names. Does
it make sense to add this feature to this tool?

Thanks.
