Patch for addr2line to add one line printing

Patch for addr2line to add one line printing

I needed a tool to convert the addresses of a stack backtrace to function names.
addr2line is the right tool to do this, but the output is not optimal for a
backtrace.

I added an option (-o) to print the result in one line. Then I found this could
be usefull for others, too.

Attached is a patch, which adds the -o option.

Best Regards,
    Reinhard

Why adding obscure options for special cases, when the same results
can be achieved by a simple awk script like:

addr2line -Cfse executable addr1 addr2 addr3 ... | \
    awk '{ if (a++ % 2) print b " " $0; else b = $0 }'

In my opinion, a format option, if added, should be more generic, like
the '+' option for the date command.
