config/arch: always select the adequate bitness Even if the selected ARCH does not support different bitness (or we do not support building with another bitness), still select the appropriate bitness.

arch/arm: add support for noMMU Some ARM cores do not have an MMU (eg. Cortex-Mx and Cortex-Rx series). Thus, allow the user to configure out the MMU for ARM.

arch/arm: add THUMB interworking support Add config option to build wtarget code with THUMB interworking. This is used to build the C library as well as all other code that runs on the target.

Excerpt from the gcc manual:
> Generate code which supports calling between the ARM and Thumb
> instruction sets. Without this option the two instruction sets
> cannot be reliably used inside one program. The default is
> [not to use interwork], since slightly larger code is generated
> when [interwork] is specified.
