Reduce code size for AVR ( #116 )
...
* all: add support for specifying target CPU in target config
* avr: specify the chip name in the target CPU
This reduces code size by a large margin. For examples/blinky, it
reduces code size from 1360 to 1266 when compiling for the Arduino Uno
(94 bytes, or ~7%).

avr: add support for the digispark
...
Blinking the on-board LED works. Nothing else has been tested yet.

avr: link with the GCC runtime library
...
This allows the use of some compiler-generated builtins that are
hopefully compatible with LLVM. Example: println(uint8(foo))
Code size is unchanged normally but of course compiler builtins will
increase code size when actually used (for example with division).

all: implement tinygo flash command

This will now just work:
tinygo flash -target=arduino examples/blinky1

This makes sure the compiler itself can build/link an ELF file that
works on an Arduino.

all: make targets configurable with a JSON file

This is intentionally similar to the target specifications in Rust:
