ac4e838289 powerpc: Remove POWER7 strncasecmp optimization 
These routines are not extensively used (gnulib documentation even
recommend use a replacement [1]), and there is already a POWER8
version that uses proper vectorized instructions.

[1] https://www.gnu.org/software/gnulib/manual/gnulib.html#C-strings

Checked with a build for some powerpc variations.

a46bb1523d powerpc: Remove strncmp variants 
The default, power4, and power7 implementation just adds word aligned
access when inputs have the same aligment.  The unaligned case
is still done by byte operations.

This is already covered by the generic implementation, which also add
the unaligned input optimization.

Checked on powerpc-linux-gnu built without multi-arch for powerpc,
power4, and power7.

68122d8a04 powerpc: Remove powerpc32 bzero optimizations 
The symbol is not present in current POSIX specification and compiler
already generates memset call.

f82ed45d7f powerpc: Use generic wcsrchr optimization 
This patch removes the power6 wcsrchr optimization and uses generic
implementation instead.  Currently, both power6 and power7 IFUNC variant
resulting binary are essentially the same and the generic implementation
with unrolling loop set to 8 also results in similar performance.

10169938b1 powerpc: wordcopy/memmove cleanup for ppc32 
This patch cleanup some multiarch code related to memmmove
optimization. Initial IFUNC support added specialized wordcopy
symbols which turned in local IFUNC calls used by memmove default
implementation.  The patch removes the internal IFUNC for wordcopy
symbols and uses local branches in the memmmove optimization instead.
