Adhemerval Zanella 19c4bec0f4 PowerPC: ifunc improvement for internal calls
This patch changes de default symbol redirection for internal call of
memcpy, memset, memchr, and strlen to the IFUNC resolved ones.  The
performance improvement is noticeable in algorithms that uses these
symbols extensible, like the regex functions.
