Title: Change echo for printf

rationale:
http://unix.stackexchange.com/questions/65803/why-is-printf-better-than-echo

When doing ```make help``` on my setup it printed the newline characters as ```\n``` Like this:
```
- [AUTODETECTED] Size utility: Basic (not AVR-aware)
-------------------------
\nAvailable targets:\n make - no upload\n make upload - upload\n make clean - remove all our dependencies\n make depends - update dependencies\n make reset - reset the Arduino by tickling DTR on the serial port\n make raw_upload - upload without first resetting\n make show_boards - list all the boards defined in boards.txt\n make monitor - connect to the Arduino's serial port\n make size - show the size of the compiled output (relative to\n resources, if you have a patched avr-size)\n make disasm - generate a .lss file in build-cli that contains\n disassembly of the compiled file interspersed\n with your original source code.\n make verify_size - Verify that the size of the final file is less than\n the capacity of the micro controller.\n make eeprom - upload the eep file\n make raw_eeprom - upload the eep file without first resetting\n make burn_bootloader - Burn bootloader and/or fuses\n make help - show this help\n
```
Changed to printf and it prints properly here.
