libgcj uses addr2line to map a PC value to a file name and line
number.  This makes for very convenient stack traces.

c++filt is of course used to demangle symbols so that they are
readable.

It would be great if we could merge the libgcj Throwable with
Classpath's.  Perhaps this could be done by separating it into a
VM-independent and a VM-specific piece.
