I have a lot of boards I could add, Nucleo's for example. Are you interested?

Would it be an idea to also optionally generate .bin and .hex files?

These images can be a great tool to quickly validate the next step, i.e. uploading and running. One approach could be to rename the bin/ directory to build/ (it's not really a "bin" you'd want to add to any PATH env, after all), and then create extra pseudo targets for "bin" and "hex" to build the requested format for all the images.

A full build for testing then becomes this one-liner: make all bin hex

The STM32L011K4 is the smallest µC with only 2 KB RAM. The current 4K setting in ld.stm32.basic does not work, changing it to 2K fixes this.

There is also another issue: the LED blinks way too fast. The datasheet says it starts up at 2 MHz, the STM32L0_CFLAGS line in boards.stm32.mk needs to be adjusted: with -DLITTLE_BIT=50000 instead of -DLITTLE_BIT=10000, things would be more in line with the rest.
