RTEMS: Fix MPC8540 multilibs for PowerPC

GCC generates SPE instructions even if -msoft-float is specified.
Explicitly add -mno-spe to prevent generation of SPE instructions.  This
multilib variant must not lead to a usage of the SPE.

gcc/ChangeLog

* config/rs6000/t-rtems: Add -mno-spe to soft-float multilib for
MPC8540.
