Subject: Change BOARD_SPEED to BOARD_CLOCK setting and extend to menu.clock
 and menu.speed. This is needed to specify CPU speed and fuses for boards.txt
 files that use this format:
 "{board_tag}.menu.clock.{board_clock}.build.f_cpu"
 "{board_tag}.menu.clock.{board_clock}.bootloader.low_fuses"
 "{board_tag}.menu.clock.{board_clock}.bootloader.high_fuses"
 "{board_tag}.menu.clock.{board_clock}.bootloader.extended_fuses" For example
 ATtiny processors.

It also works for speed-only settings like the Watterott ATmega328PB library: https://github.com/watterott/ATmega328PB-Testing
"{board_tag}.menu.speed.{board_clock}.build.f_cpu"
