kbuild: fix a compile warning

gcc-4.4.1: HOSTCC scripts/basic/fixdep scripts/basic/fixdep.c: In function 'traps': scripts/basic/fixdep.c:377: warning: dereferencing type-punned pointer will break strict-aliasing rules scripts/basic/fixdep.c:379: warning: dereferencing type-punned pointer will break strict-aliasing rules (Apparently -fno-strict-aliasing will fix this too)
