I ran into a few small-but-important issues doing the "hello world" equivalent on an arduino nano after installing the arduio-bsk-mk tools.
First part was getting the Makefile correct.
First thing I did was set the ARDUINO_BOARD. That led me to an error with a missing -mmcu parameter from GCC. Setting MCU fixed that. One other trick was making the main source file name the same as the project eg. 'arduino1.ino'.
That was enough do to a 'make' from the shell. Running 'make install' to program the nano came with some issues too. Setting port permissions was easy enough. However, I was seeing errors related to include baud rate for '-P'. Took me a while to realize the baud rate parameter '-b' appeared just before the '-P' parameter. The '-b' argument ate the next argument. Setting ARDUINO_SPEED fixed that.
Next up was an error from avrdude complaining of a lack of a /usr/local/etc/avrdude.conf file. I ran a search using find, and found an avrdude.conf file under /usr/local/arduino/hardware/arduino/avr/bootloaders/gemma/avrdude.conf. I copied this to /usr/local/etc/ and now ...
Now the nano blinks as expected.
I'm currently stuck getting the Arduino 1.8.5 IDE to recognize my ttyU0 port but at least the hardware is confirmed working from a shell prompt.

avrdude done. Thank you.Now the nano blinks as expected.
