build-all.sh status messages and ability to resume previous run.

Enhanced build-all.sh to:
- Print the messages logged to ALL.out, to keep track of progress
- Print an error message when it fails, with a hint to what failed
- Keep track of packaged that build successfully, and if build-all failed:
- Skip packages that were build successfully in the previous run.
