[PATCH] time: posix-stubs: provide compat itimer supoprt for alpha

[Arnd Bergmann]

Using compat_sys_getitimer and compat_sys_setitimer on alpha
causes a link failure in the Alpha tinyconfig and other configurations
that turn off CONFIG_POSIX_TIMERS.

Use the same #ifdef check for the stub version as well.
