Now that muser-mode is default the multilib definitions does not

specify that switch any more. Add UT699 to multilib after recent
patches. Add
AT697F multilib since there are many LEON2 users running RTEMS.

* config/sparc/t-rtems: Remove -muser-mode, add ut699 and at697f

Why do we need so many variants with fixes for the UT699 (32-bit
Fault-Tolerant LEON3FT SPARC V8 Processor) and the AT697F (LEON2-FT)?
Why do we have no leon3 variant without fixes for the UT699 and
AT697F? Which multilib do you suggest now for the NGMP/GR740?
Sorry, for these stupid questions. Maybe we should change this file to
use MULTILIB_REQUIRED, like on rs6000 and arm.
Which multilibs do we have after this change?
