See YottaDB/DB/YDB!1423 for
reasoning.

NB:
1. We tied every plugin repo to this repo using a hash to assure
   reproducible builds. The following repos need to have commits made:

- YDBSyslog
- YDBSodium
- YDB-Web-Server
- YDBOcto
- YDBPosix
- YDBGUI
- `ydbinstall.sh` needs to check for ld.gold instead of gcc for all
  plugins.

2. If you want to reuse an existing build directory with this new
   version, I haven't really found a way to do that except by manually
   editing `CMakeCache.txt` in the build directory and remove the `CC`
   entry.
