Subject: [PATCH 1/2] Remove toolsDependencies entries

This change is required due to a bug in the Arduino IDE which causes the
tool versions specified by avr_boot to be used by other platforms such
as Arduino AVR Boards after Boards Manager installation of avr_boot(see
https://github.com/arduino/Arduino/issues/5168). A specific issue caused
by this is that Arduino AVR Boards 1.6.12  requires LTO support, which
avr-gcc does not have. This will cause Arduino AVR Boards to no longer
compile when the previous version of package_zevero_avr_boot_index.json
was used to install avr_boot.

Removing the toolsDependencies entries causes avr_boot to use whatever
tool versions were previously installed.

The disadvantages of this solution are:

- Breaks compatibility with the Eclipse Arduino plugin(see
https://github.com/jantje/arduino-eclipse-plugin/issues/516), which
requires these entries.

- Loss of control over the specific toolchain used.

Subject: [PATCH 2/2] Add Arduino AVR Boards 1.6.12 incompatibility warning

Arduino AVR Boards 1.6.12 upgraded avrdude to avrdude 6.3.0-arduino2.
avrdude's handling of unused fuse bits has changed since the previous
version Arduino used(6.0.1-arduino5) which causes the ATmega328P
extended_fuses value to fail verification(see
https://github.com/arduino/Arduino/issues/5175) and the unlock_bits and
lock_bits values to fail verification when used with Atmel AVRISP mkII
and likely any other stk500v2 based programmer(see
https://github.com/arduino/avrdude-build-script/issues/2). Fixing these
issues while maintaining backwards compatibility with previous Arduino
AVR Boards versions would be possible by adding an avrdude tool to
avr_boot but the Arduino developers have decided to revert to the
previous avrdude version on the soon to be released Arduino AVR Boards
1.6.13 and only upgrade to a new avrdude version once it has been
modified to work with the traditional Arduino fuse values(see
https://github.com/arduino/Arduino/pull/5161 and
https://github.com/arduino/Arduino/pull/5202). This makes me think that
the extra complexity of adding an avrdude tool is not worth the benefit
of providing compatibility with a single buggy Arduino AVR Boards
version.
