bare-metal: Add STM8 architecture for SDCC toolchain

Previous implementation of SDCC toolchain based on an assumption,
that the default target architecture always is MCS51.

But, the SDCC compiler support multiple architectures:

* http://sdcc.sourceforge.net/

So, it is makes sense to add support and for STM8 architecture
to the SDCC toolchain.
