Deciding whether to compile the env_sf_save() function based solely on CONFIG_SPL_BUILD is wrong: For U-Boot proper, it leads to a build warning in case CONFIG_CMD_SAVEENV=n (because the env_save_ptr() macro causes the function to indeed not be referenced anywhere). And for SPL, when one selects CONFIG_SPL_SAVEENV, one obviously expects to actually be able to save the environment.
