commit dcaf7fedb9a2aab91cd87d3fa9128c25fe8d2eb5
Author: Sebastian Huber <sebastian.huber@embedded-brains.de>

    Use external header file for kernel space types
    
    The FreeBSD kernel types are not used in Newlib.  Provide them via an
    external header file to decouple Newlib and FreeBSD updates for RTEMS.
