[v5 1/2] lib/raid6: Build proper files on corresponding arch

[Matt Brown <matthew.brown.dev@gmail.com>]

Previously the raid6 test Makefile did not correctly build the files for
testing on PowerPC. This patch fixes the bug, so that all appropriate files
for PowerPC are built.
This patch also fixes the missing and mismatched ifdef statements to allow the
altivec.uc file to be built correctly.
