Modified the linker so that it always links in an object from an archive
...
that defines the symbol "main." This is a hack that ensures that programs
that place their main function in a library and then link it in

There is probably a more correct way to do this, but this works for now.

Make "verbose" output MUCH nicer. Now it tells you when you are linking a
