sysctl: Enable IA64 "ignore-unaligned-usertrap" to be used cross-arch
IA64 defines /proc/sys/kernel/ignore-unaligned-usertrap to control verbose warnings on unaligned access emulation. Although the exact mechanics of what to do with sysctl (ignore/shout) are arch specific, this change enables the sysctl to be usable cross-arch.
