Tool bundle updates (#693)

* Pre-commit --cached vs. less-efficient iteration

 * During pre-commit, leverage the git cppcheck --cached
   form instead of iterating over the cached files and
   invoking git cppcheck on each to eliminate
   redundant static analysis

* Add support for Debian Linux on ARM

* Check prerequisite tool minimum versions

 * Bootstrapping will now confirm that each
   prerequisite tool satisfies the minimum version
   required
