If flang were to check for quad-precision support at "use-time", .i.e. when flang is being **used** to compile some code, then wouldn't flang itself *always* have to be built with everything needed to support `kind=16`? So `ieee_arithmetic.mod` would always have to be built with support for `kind=16`? Is my understand of this correct?
