Update to ELF Tool Chain r3477
This fixes a EFI/PE header issue that prevented elfcopy-produced .efi
files from working with Secure Boot:
Make sure section raw size is always padded to multiple of FileAlignment from the optional header, as requested by the PE specification. This change should reduce the diff between PE image generated by Binutils objcopy and elftoolchain elfcopy.
