George Oikonomou cb075dec65 Disable SDCC warnings 110 and 126
Those two warnings are optimisation-related
* 110 warns that an always-false if branch has been optimised out
* 126 warns about unreachable code which also gets optimised out

In disabling those warnings, we make the build less cluttered
