Thank you for quick update.

With newer ubuntu on host I'm seeing one more issue with bazel-native,
will send a patch or more details when I figure out what's wrong, but
it fails with ubuntu-25.04 and newer while in ubuntu-24.04 and 24.10
it built bazel-native fine.

I'm sharing it now just in case you've already seen this issue and
might have some pending fix already.

The log from 24.04 doesn't show "Linking src/main/cpp/util/libport.a"
at all, so I guess it's util:port dependency somehow not required, but
I'm still searching why (in all that bazel output which is a bit
confusing to me :)).

Regards,
