powerpc: Fix powerpc64 build failure with binutils 2.22
GLIBC memset optimization for POWER8 uses the '.machine power8'
directive, which is only supported officially on binutils 2.24+. This
causes a build failure on older binutils.
Since the requirement of .machine power8 is to correctly assembly the
'mtvsrd' instruction and it is already handled by the MTVSRD_V1_R4
macro, there is no really needed of using it.
The patch replaces the power8 with power7 for .machine directive.
It fixes BZ#17869.
