[libunwind] thoughts for future development

[Richard Henderson]

At present, there's a whole lot of busy work that one must 
perfom to port to a new target.  I think the sets of things
that would help here are:

(1) Remove the L*.c files.  All these object files can be
    built via makefile rules.

(2) Reorganize the dwarf code such that more of the code
    is shared.  In particular, the missed initialization
    bug fixed yesterday shouldn't have been able to happen.

I'll be working on this shortly, as well as adding support
for a good many more targets.
