With a backported version of wasi-libc, which I forgot to upload
apparently because of a delay between the build and upload.

Done that now, I will trigger a rebuild once it is in the back ports
archive. AFAIK, dak is now properly configured to throw away
the maintainer built binaries needed for NEW, so this should be
caught automatically in the future! somewhat ironically, I waited
with the 1.90 upload for that dak change to get active, but the first 
attempt there was still broken..

Thanks a lot for your report!
