It seems that tinygo doesn't not support MIPS based embedded devices out of the box, although LLVM does support the following:

    mips       - MIPS (32-bit big endian)
    mips64     - MIPS (64-bit big endian)
    mips64el   - MIPS (64-bit little endian)
    mipsel     - MIPS (32-bit little endian)

My intent is to execute the tinygo compiled binary within a mipsel linux box, no

packBEAM should be also implemented in Erlang, so it can be integrated into existing Erlang and Elixir tooling in a easier way.

Create a new C# class library that "taps" into the existing native methods and makes them available to managed apps.
