arm bsps: changing the float-abi to softfp

Hello Ingolf,

the -mfloat-abi=softfp instructs the compiler to emit floating-point 
instructions if other machine options specify a FPU. Why would you use 
this instead of -mfloat-abi=hard? For a statically linked executable 
this makes little sense. You still have to take care of the FPU context 
during context switches and interrupt processing.

If you really need such a multilib, then you can patch 
gcc/config/arm/t-rtems. I don't know if you can add custom patches to 
the RTEMS Source Builder.
