b[l]x instruction in cortex-m3 code

Hi,
when I link code for the ARM Cortex-M3 the b[l]x instruction is emitted.
Since Cortex-M3 has no ARM mode and no b[l]x instruction the CPU goes in a fault
mode when it is asked to execute it.

As far as I have read it is ok for the compiler to emit b[l]x but the linker is
required to translate it into b[l] instructions.

I tried a lot of linker flags with no success.

Are I'm missing something or is this really a bug?

Best regards,
  Daniel Otte
