Well, maybe I'll make one after I figure out why 'asin' test halts half its
way as soon as I build all with -mhard-float flag :-( Hopefully it just causes
floating point exception at some value from the test vector, and the exception 
isn't yet handled properly.

I think the test for HAL FPU support should run 3 threads at the same
priority level that are time-sliced. Two of these threads should perform
floating point computations, and one should not use floating point (to test
not yet implemented lazy FPU context switches). I also think this test belongs 
to 'hal/common' set.

Any comments?

Sergei.
