Sometimes substitution looks acceptable:

> -obj-y += $(nfsd-y) $(nfsd-m)
> +obj-y-if-$(CONFIG_NFSD) += nfsctl.o
obj-$(CONFIG_NFSD:m=y) += nfsctl.o
But for the nontrivial cases, things get pretty ugly:
> -ifeq ($(CONFIG_PROC_FS),y)
> -obj-$(CONFIG_LOCKDEP) += lockdep_proc.o
> -endif
obj-$(CONFIG_PROC_FS:y=$(CONFIG_LOCKDEP)) += lockdep_proc.o
