builder request: Octave

[Krastanov]

Having Octave available in Yggdrasil will make the creation of simple matlab-translation tools a bit easier (OctaveCall.jl akin to PythonCall.jl and MATLAB.jl). Creating this issue here to track potential progress.

[ViralBShah]

I suppose this should be straightforward to build, but may need a bit of work to use all the dependencies from Ygg itself.

[ViralBShah]

I believe this is not straightforward because the Octave build process did not support cross-compilation. This was a while ago, and perhaps things have changed.

[ViralBShah]

We do have an interface package, but it will need a significant refresh since it uses Cxx.jl. https://github.com/JuliaInterop/OctCall.jl

[imciner2]

Octave was added inhttps://github.com//pull/9729, so closing this.

[ViralBShah]

The produced binaries have some issues - but yes at lesat we have the builder.

Minor nitpick: I warmly recommend using addenv over withenv, the former is thread-safe, the latter isn't. I personally had bad experiences with withenv, if the process dies unexpectedly, you can end up with a broken ENV which breaks everything.
