Add support for compiling plain AVR C files
To compile plain AVR C files, the variable NO_CORE should be initialized to a non-empty value. When NO_CORE is set, the following changes happen - boards.txt file is not parsed. The user should explicitly set MCU, F_CPU, fuse bits etc. - MONITOR_BAUDRATE is not calculated Fix #63
