OK, it turns out the built myself autotools were not the problem, I 
still have a compile fail at cpulit/posix/src/pthread.c

Error below:

This "struct sched_param" is defined in the compiler rtems includes from:

/opt/rtems-4.10/arm-rtems4.10/include/sys/sched.h as:

And it does not have the extra parameters defined.

It looks like the prebuilt mingw tools are out of sync with the 4.10 source.

We can built this bsp using Ubuntu where the tools were built in house 
using all the RTEMS patches.
