You can not use that toolset to build RTEMS (without much special
handwaving :).  You would have to tell it to ignore all of its own
header files and libraries.  RTEMS POSIX/BSD support is a fine balance
between newlib and RTEMS itself.  If you do not have the proper toolset,
then you will have great difficulty building RTEMS.

As an aside, there are users who have built RTEMS in similar situations
with other non-RTEMS toolsets (both GNU and non-GNU).  There is a
certain
amount of special "magic," that I wouldn't even know where to begin.
Anyone out there who has done it willing to explain/give hints?
