    Bug 22361: fix hardening of libraries built in linux/gitian-utils.yml
    
    With the changes to integrate Selfrando (#20683), we are using our build
    of gcc and binutils to build other libraries in the linux/gitian-utils.yml
    descriptor, which removed the use of the hardening wrappers. We fix that
    by adding the hardening wrappers to our builds of gcc and binutils.
    Because we add the wrappers to gcc and binutils zip files, we don't need
    to add them anymore in the other descriptors where they are used.
