selftests/powerpc: Add test for 32 bits memcmp
This patch renames memcmp test to memcmp_64 and adds a memcmp_32 test for testing the 32 bits version of memcmp() Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> [mpe: Fix 64-bit build by adding build_32bit test] Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
