It's worth noting that 0ad build-depends on nvidia-texture-tools in
Debian, so we can ignore the embedded copy of nvtt in 0ad's source.

Would you consider filing this bug report directly upstream [1][2],
with your patch (just like you did with nvidia-texture-tools)? I'm not
a porter myself and I don't think there's any value in me being a
middleman, in case upstream has any questions to ask you etc. Thanks!
