Macro rustc_link_arg_bins

macro_rules! rustc_link_arg_bins {
    ($($tokens:tt)*) => { ... };
}

The rustc_link_arg_bins instruction tells Cargo to pass the -C link-arg=FLAG option to the compiler, but only when building a binary target. Its usage is highly platform specific. It is useful to set a linker script or other linker options.
