    tests: Disable link-time warning for mem-overflow
    
    `mem-overflow` test disables GCC warning `alloc-size-larger-than` via
    diagnostic pragma, but it's still emitted in the linkage stage when
    LTO is enabled.
    
    This changes explicitly set `link_args` for the test to disable the
    warning.
