[PATCH, committed] PR target/81084: Hide more irrelevant powerpcspe options

[Andrew Jenner]

I have committed this patch to suppress some more irrelevant options 
from the output of "gcc --target-help" for the powerpcspe backend.

I have tested this by rebuilding GCC and checking the output of "gcc 
--target-help".

         * config/powerpcspe/powerpcspe.opt: (msimple-fpu, mfpu) Add 
Undocumented.
         * config/powerpcspe/sysv4.opt (mbit-align): Likewise.
