This is really a never ending story:

/build/rtems/6/lib/gcc/arm-rtems6/10.2.1/../../../../arm-rtems6/bin/ld: 
/build/rtems/6/lib/gcc/arm-rtems6/10.2.1/../../../../arm-rtems6/lib/thumb/armv7-a+simd/hard/libm.a(lib_a-fesetenv.o): 
in function `fesetenv':

undefined reference to `vmsr_fpscr'

I will fix it.
