cc3200: Fix bootloader and modpyb after printf overhaul.

Daniel Campora · Daniel Campora · commit df5d9c77f4a7 · 2015-04-19T20:59:10.000+02:00
The bootloader needs string0.c because of memset, memcpy and others,
without string0.c it magically links, but calling any of those
functions results in a hard fault.
In debug mode, modpyb needs printf, and including stdio.h leads to
conflicts due to the redefinitions made in the simplelink drivers.
