* 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
* Using LIBRARY=[avr|gnu] git cppcheck ... will set the command
line library= to the value
* Using PLATFORM=[avr.xml|unix32.xml] git cppcheck ... will set
the command line platform= to the value
* Corrected logical if error when bootstapping a pristine repo
References #672
* The Arduino IDE considers the .tools directory
special and warns if it finds .tools the repo
* Added detection of .tools directory rename
* Corrected README errata
