>Configuring and building gcc 4.8.2 for the target 'arm-none-eabi' results in a

That is correct. The default is to configure arm target to be armv5 processor.
You need to configure for building for armv6m or an armv7m (or even armv7-a)
if you want to use -mthumb for a thumb (or thumb2 only) processor.
