[PATCH] powerpc: Use latest optimizations for internal function calls

[Rajalakshmi Srinivasaraghavan]

Some of the power8 strings optimizations are not updated to use the latest
version of other string optimizations.

Tested on powerpc64 and powerpc64le.

2017-02-05  Rajalakshmi Srinivasaraghavan  <raji@linux.vnet.ibm.com>

	* sysdeps/powerpc/powerpc64/multiarch/strcasestr-power8.S: Redefine
	STRCHR as __strchr_power8.
	* sysdeps/powerpc/powerpc64/multiarch/strcat-power8.c: Redefine
	strlen as __strlen_power8.
