micropython/py/py.mk
Damien George 0be2ea50e9 py/py.mk: Build axtls library directly from its source files. 
This removes the need for a separate axtls build stage, and builds all
axtls object files along with other code.  This simplifies and cleans up
the build process, automatically builds axtls when needed, and puts the
axtls object files in the correct $(BUILD) location.

The MicroPython axtls configuration file is provided in
extmod/axtls-include/config.h
