IIRC, libaddr2line has never been part of the official binutils, and
it's source code has not been released (probably by accident, but
still).

J�rgen Pfeifer wrote GNAT patches that invoke /usr/bin/addr2line to
resolve the addresses.  This approach avoids the dependency on the BFD
library and is cleaner.  Of course, it's a bit slower.

I'm not sure what the Java front end does.  This code should probably
be reused.
