Packages built on WSL 2.0 get uploaded as Windows not Linux conda packages

[gb119]

I have a conda-buid setup on my WSL 2.0/Ubuntu 20.04 for packaging various python libraries. I'm trying to package them as linux-64 conda packages for deployment to a remote virtual machine where I don't really have the capacity to do the build directly. I can see in the WSL environment that my packages are ending up in conda-bld/linux-64/ but when I look in the files in my channel in anaconda.org, I only see Win-64 tagged files. It looks like something in the upload process is failing to correctly identify that I'm on a WSL environment and I can't see anyway of manually overriding. (This is uploading with anaconda upload CLI via anaconda_upload: true in my .condarc).
