efi_loader: use freestanding library for efi apps
GCC requires that freestanding programs provide memcpy(), memmove(),
memset(), and memcmp().
Add the library functions when building a *.efi files.
The EFI selftests might use other compilation flags. So use a symbolic
link to provide lib/efi_selftest/efi_freestanding.c and compile it
separately.
