Thomas Weißschuh ff7b9abbfc tools/nolibc: stackprotector: mark implicitly used symbols as used ...

During LTO the references from the compiler-generated prologue and
epilogues to the stack protector symbols are not visible and the symbols
are removed.
This will then lead to errors during linking.
As those symbols are already #ifdeffed-out if unused mark them as "used"
to prevent their removal.
