Rtems-4.10.2 and RPC on PowerPC

[Kate Feng]

I applied PR 1786, and PR 1797 to RTEMS4-10.0.

https://www.rtems.org/bugzilla/show_bug.cgi?id=1786
https://www.rtems.org/bugzilla/show_bug.cgi?id=1797

In addition, for RTEMS4-10.0, one needs to apply the patch below for the
cpukit/libfs/src/nfsclient/src/nfs.c

Yes,  RTEMS4.10.1 and RTEMS4.10.2 still have bugs.
