[PATCH, committed], Fix typo in gcc/config/rs6000/rs6000.md

[Michael Meissner]

Since I committed the rs6000 -mrecip support last June, there has been a
harmless typo in the source.  I had spelled RS6000_RECIP_HAVE_RSQRTE_P as
RS6000_RECIP_HAVE_RSQRT_P.  The build would note that RS6000_RECIP_HAVE_RSQRT_P
was not defined, and generate a call to the unknown function.  However, this
warning would not stop a make bootstrap.  The linker would dutifully enter a
call to RS6000_RECIP_HAVE_RSQRT_P to be filled in later, but since the
gen_rsqrt* functions were never called, the typo was never noticed.  Andreas
Tobler prompted me to look into it, and I fixed it as being obvious.  I did do
a bootstrap build before checking it in.
