Fix warnings treated as errors with W=1:
arch/powerpc/lib/sstep.c:1172:31: error: variable 'rc' set but not used [-Werror=unused-but-set-variable]
Suggested-by: Christophe Leroy <christophe.leroy@c-s.fr> Signed-off-by: Mathieu Malaterre <malat@debian.org> --- v2: as suggested prefer CONFIG_PPC64 sentinel instead of unused keyword
