MPC8260 not recognized

[Leon Pollak]

Hello,

1. Thanks to Ralf for the previous help. As the result I am now at the RTEMS 
source compilation phase.

2. I downloaded prebuilt tools for PPC for 4.7 and sources for 4.6.99.3 and 
try to compile my copy of the MPC8260FADS BSP (after running bootstrap).
The error I received is (from config.log):

Here I am lost... How the correctly compiled gcc with tested MPC8260FADS BSP 
can not recognize this option?

Many thanks ahead.
