arm bsps: changing the float-abi to softfp

My goal is to link with a 3rd party object file which had been compiled with -mfloat-abi=softfp and which cannot be recompiled. In fact, there are also other flags which might cause a conflict with the current flags used by RTEMS and which might cause even more headache (-mfpu comes to my mind).

I assume that I could add them to the corresponding config/tools/*.cfg.

Kind regards
