`avr-size` was defaulting to AVR non-aware when using ARM builds, which
meant passing .hex rather than .elf to size and limiting size readout.
Adding a switch for defining `avr-size` and SIZEFLAGS to Sam.mk seems
like the best way to include proper ARM support (despite conflicting
naming).
Currently three different tool chains seem to be used:
* avr-*
* pic32-*
* arm-none-eabi-*
These all get set up independently. This patch centralizes the
definitions of the executable tools and does it generically, by means
of the newly introduced TOOL_PREFIX variable. Setting up a
tool chain is now simply a matter of defining the TOOL_PREFIX
variable. For the currently supported tool chains it gets set to avr,
pic32 or arm-none-eabi. Arbitrary tool chains can now easily be set up,
by the TOOL_PREFIX variable.
Although the use of the OVERRIDE_EXECUTABLES variable is now almost
not justifiable, it was left as-is, in order to assure backwards
compatibility.
Compilation improvements by adding variant as other obj but not working on device
Arduino Zero devices with OpenOCD working
Created ARM_TOOLS_DIR and define arm toolchain executables in Sam.mk

Documentation updates and define ARDMK_VENDOR rather than include Sam.mk
Expand all parse_boards when defined rather than when used
Trim extra defines regex working on both macOS and Linux but need better fix
Print USB ids and added debug usage to readme
Add note on Arduino package dir and made board.txt work
Do ARM ARDUINO_ARCH define in Arduino.mk]
Add MZeroBlink to non-testable examples for now
Remove \B from extra defines grep

SAMD bootloader support in ard-reset using --zero
Enters bootloader using open/close of port at 1200 BAUD, then polls the
attached devices for new port enumerating (bootloader). This is how the
Arduino IDE operates
