Charlie Varanet recently released Uno, an optimization solver that can use MA57 as a linear solver.
However, just like GALAHAD, Uno needs the symbols of MA57 at compilation time (JuliaPackaging/Yggdrasil#8937).
We should add dummy subroutines for the following symbols so that users can rely on HSL_jll.jl as we do with Ipopt.jl and, in the near future, GALAHAD.jl:

ma57id_
ma57ad_
ma57bd_
ma57cd_
ma57dd_

I think the following code should be enough:

SUBROUTINE MA57ID()
END SUBROUTINE MA57ID

SUBROUTINE MA57AD()
END SUBROUTINE MA57AD

SUBROUTINE MA57BD()
END SUBROUTINE MA57BD

SUBROUTINE MA57CD()
END SUBROUTINE MA57CD

SUBROUTINE MA57DD()
END SUBROUTINE MA57DD

or do we need to provide dummy subroutines with all arguments?

It's the dummy version that I will precompile with Yggdrasil.
