    nvramcui: Update Makefile
    
    - Add all, clean and distclean to .PHONY
    - Rebuild nvramcui.elf when the makefile changes.
    - Update libpayload target to $(LIBPAYLOAD_DIR) target - these are the
    same thing, but by using the variable it makes it more obvious.
    - Remove .config.old as well as .config when running distclean.
    - Add CFLAGS to the LPGCC command line:
    -- Enable all warnings, set warnings as errors.
    -- Optimize for size
    -- Enable '-ffreestanding -nostdinc -nostdlib' to keep from building in
    system functions and to fix the warning:
    libpayload.h: warning: conflicting types for built-in function 'log2'
    static inline int log2(u32 x) { return sizeof(x) * 8 - clz(x) - 1; }
