build: Drop implicit-fallthrough to allow older build compilers #181

Closed Andre-ARM closed 3 years ago

Andre-ARM commented 3 years ago

-Wimplicit-fallthrough was introduced in GCC 7, so currently building crust requires all three involved compilers to be at least of that vintage.

While it's somewhat feasible to upgrade to a newer cross-compiler, the system compiler is much harder to update on its own, especially in long term stable distributions.

To allow building crust on older Linux systems without extended surgery, drop the new warning option from the "build" compiler flavour. Actually it is explicitly disabled again when building Kconfig, so we don't really lose anything.
