This avoids that Modelica utility function ModelicaError has to be provided by library ModelicaExternalC.

@beutlich can you quickly describe what is the advantage of this solution? Thanks!

Currently MSL requires that tools provide a library (static or dynamic) named "ModelicaExternalC.*" where symbol "ModelicaError" gets resolved. However, this is not required from MLS perspective. This PR fixes this superfluous requirement.

Is this related to #4476? If so, we should probably try to get a harmonized solution. Or is this an orthogonal issue?

I'd rather consider this an orthogonal issue. The current external function of Stream.error uses some kind of short-hand of ModelicaError being exposed of library ModelicaExternalC. However ModelicaExternalC is provided by MSL (and not specified in MLS) whereas ModelicaError is provided by vendor-specific ModelicaUtilities.
