fs/proc: Add compiler check for -Wno-override-init to support gcc < 4.2
With gcc < 4.2 (e.g. 4.1.2):
CC fs/proc/task_mmu.o
cc1: error: unrecognized command line option "-Wno-override-init"
To fix this, only enable the compiler option when it is actually
supported by the compiler.
Fixes: ca52953f5f24 ("fs/proc/task_mmu.c: suppress compilation warnings with W=1")
