RFR: 8284437: Building from different users/workspace is not always deterministic

[Andrew Leonard]

This PR fixes the non-deterministic behavior when building on linux with different userids or within
different workspace folders.
It fixes the following issues:
- MakeZipReproducible.java used to produce reproducible src.zip removes the optional zip "extra" field containing UID/GID.
- When absolute output paths are not allowed, enable the use of -fdebug-prefix-map to ensure debug symbol info does not contain the top level workspace folder.
- For reproducible builds ensure the gcc random symbol name generator is seeded using -frandom-seed.
- For reproducible builds when producing debug symbols use relative object paths for library linking to remove absolute MASM object paths.
