[Question] Emscripten and linker scripts

I currently have a shared library which in order to link to a main_module I have to export a large list of symbols

As part of the review of the PR where I include this large list of symbols to be added as link flags I got asked the following question

I can find no reference to linker scripts in the documentation. As someone who has never used them before even for native builds, I thought I would double check that Emscripten does support them before I start the work of working out how to construct an equivalent linker script to what I am currently doing. Can someone confirm if they are supported by Emscripten or not?
