This exists as a simple way to test the address to line functionality of the
DWARF support in rtemstoolkit.

I should move this command from linkers to misc how it exists. It did not exist
when I added the support.

FYI ...

- The rtemstoolkit has cross-platform support for calling child processes. The
symbols tool for libdl is a good example of accessing symbols and then calling
child processes to do some work. It also has an example of the tmp file support.
The symbols tool creates a C file and then calls the RTEMS gcc to compile it for
your target ...

- If you need to handle complication units (CU) the executable info tool
provides a good example. It also shows how to handle sections in an ELF
executable or object file ...

It should also move to misc.

I hope these help.
