powerpc: Remove power7 strstr optimization
The optimization is not faster than the generic algorithm, using the bench-strstr the geometric mean running on a POWER10 machine using gcc 13.1.1 is 482.47 while the default __strstr_ppc is 340.97 (which uses the generic implementation). Also, there is no need to redirect the internal str*/mem* call to optimized version, internal ifunc is supported and enabled for internal calls (meaning that the generic implementation will use any asm optimization if available). Checked on powerpc64le-linux-gnu. Reviewed-by: Peter Bergner <bergner@linux.ibm.com>
