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; }
