From: Andrei Gherzan <and...@gherzan.ro>
Use thumb instructions for Cortex-M3 to avoid this gcc error:
'error: target CPU does not support ARM mode'.
Extracted from "Cortex-M3 Technical Reference Manual":
"The processor implements the ARM v7-M architecture. This includes the entire
16-bit Thumb instruction set and the base Thumb-2 32-bit instruction set
architecture. The processor cannot execute ARM instructions."
