Per Microsoft PE Format documentation [1], PointerToSymbolTable and NumberOfSymbols should be zero for an image in the COFF file header. Currently U-Boot is generating *.efi images (eg: helloworld.efi) in which these two members are not zero.
This updates the build rules to tell linker to remove the symbol table completely so that we can generate compliant *.efi images.
