On non-x86_64 builds, helpers gtod_is_based_on_tsc() and kvm_guest_supported_xfd() are defined but never used. Because these are static inline but are in a .c file, some compilers do warn for them with -Wunused-function, which becomes an error if -Werror is present. Add #ifdef so they are only defined in x86_64 builds.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
