libaddr2line.a is a library normally built from the binutils source
distribution.  GNAT relies on it for sumbolic traceback of exceptions.
Unfortunately, I am not aware of any binary distribution of GNU/Linux
that ships libaddr2line.a.  I am not even sure that recent versions of
binutils (as required by recent versions of GCC) support building
libaddr2line.a.

If you're interested, AdaCore's binary distribution of GNAT 3.15p does
include this library (from binutils-2.9.1), and does support symbolic
tracebacks.
