This test is simply latency_calibration with the use of some SIMD instructions
imported from SSE3Dnow.h, copied from project ATLAS. 
It serves to verify if SIMD register can be safely used within (NEW)LXRT.
Since kernel space RTAI tasks have the same floating point support SIMD should
be usable there too.
The making of this directory does not happen by default, you must do it
explicitly from within here. The default setting is for PIII/SSE, as
defined by the SSE macro in rt_process.c. If you have an AMD ATHLON
just comment it out before making.
