Crash under sparc/rtems-4.11 when compiling with FPU

since this issue pops up every now and then we should eventually fix it. 
My approach would be to add the following BSP variants:

leon2fp (is the LEON2 still relevant?)

Which compiler flags should we use? We have the following multi-libs 

-mcpu=leon -mfix-ut699
-mcpu=leon -mfix-at697f

I guess the compiler issue with respect to spurious FP instruction 
generation is fixed:

However, this should be checked by manual inspection of the 
librtemsbsp.a and librtemscpu.a for each new compiler version.
