[ Upstream commit bfcf4004bcbce2cb674b4e8dbd31ce0891766bac ]
I want to be sure that ipv6-specific code
is not compiled in kernel binaries
if ipv6 is not configured.
[1] was getting rid of "unused variable" warning, but,
with that, it also mandated compilation of a handful ipv6-
specific functions in ipv4-only kernel configurations:
smk_ipv6_localhost, smack_ipv6host_label, smk_ipv6_check.
Their compiled bodies are likely to be removed by compiler
from the resulting binary, but, to be on the safe side,
I remove them from the compiler view.
