On Darwin, there's a native program atos which does the same as
addr2line.

If your target is VxWorks symbolic tracebacks don't work at all; you
have to use addr2line (well, in VxWorks 5 executables are relocatable
but stack addresses are absolute; so you actually use a wrapper
{powerpc}-wrs-vxworks-vxaddr2line which works by referencing the
runtime address of adainit to its offset in the executable).
