Looks like a work in progress still, but exciting someone at least put some time into this in the past year.

Maybe some day I can have pandoc in security focused linux distributions...

This is the same process used to port GHC to new architectures, like ARM. It is not easy to do, I don't know how many people can actually do it. But its possible and has been done multiple times.

Is it? Typically compilers rely on cross-compilation for this.
