make, tmpl/tagged: Add basic microcontroller support

Browse source 
Add support for building the firmware of the Cortex M3 ST-NUCLEO-F103RB
development board with an STM32 microcontroller. This commit add some hooks,
notably support for tagged templates, but adds lots of crap, too, notably
makefiles and variables that should have different names and / or
functionality.

New makefiles are: Mcu-defs.mk  mcu-exe.mk  mcu-flash.mk  mcu-tags.mk
mcu-topdir.mk tagged-tmpl.mk, a new directory is tmpl/tagged.
