build of libbsd for powerpc fails with error: redefinition of 'eieio'

[Peter Dufault]

I have a build failure with the MVME5500 “beatnik” BSP. Therefore I tried to build the “psim” BSP and have the same failure: the FreeBSD PowerPC “cpufunc.h” and the RTEMS PowerPC “io.h” headers both define static inline "eioeio()" functions.

- RTEMS, libbsd, RSB and the build tools are up-to-date as of this AM.
- Building for arm xilinx_zynq_a9_qemu succeeds.
- I’ll work-around it but I believe I must have something locally screwed up, I can't find any recent changes associated with this.
