fix scripts
- support Rocky Linux 8 as minimum supported OS
- deprecate CentOS 7 support
- update to using a vanilla released version of crosstool
- configs should now be able to be upgraded when we go to a new version instead of having to be rebuilt
- changes to script flow to make it easier to iterate on the build process when things break
- stages of the build are checkpointed so that they don't have to be redone each run
