rs6000: Put back the 's' output modifier
It turns out the 's' output modifier is used in some glibc math code,
and is in an installed header even. So let's put it back, it is much
less of a burden supporting it a bit longer than to deal with the fallout.
(It is also being fixed for glibc.)
* config/rs6000/rs6000.c (print_operand): Rollback 's' removal.
