    UNTESTED: gnu: webkitgtk: Fix build on i686-linux.
    
    Fixes <https://bugs.gnu.org/51591>.
    
    * gnu/packages/webkit.scm (webkitgtk)[arguments]: Use quasiquote for the
    argument list.  When building on i686-linux, insert a 'substitute*' form in
    the 'prepare-build-environment' phase that disables of the use of
    '__builtin_mul_overflow'.
