arm, arm64, csky, mips, powerpc always select GENERIC_GETTIMEOFDAY, hence $(gettimeofday-y) never becomes empty. riscv conditionally selects GENERIC_GETTIMEOFDAY when MMU=y && 64BIT=y, but arch/riscv/kernel/vdso/vgettimeofday.o is built only under that condition. So, you can always define CFLAGS_vgettimeofday.o Remove all the meaningless conditionals.
