Building HAT: error, missing file?

[Juan Fumero]

Tracing back, on my system fails after this commit:

https://github.com/openjdk/babylon/commit/82e0e551b6d8db1ccef7c00f52f7fdc786400962

```
$ cd hat
$ . env.bash
$ java @bldr/args bld
Note: /tmp/babylon/hat/bldr/Bldr.java uses preview features of Java SE 24.
Note: Recompile with -Xlint:preview for details.
jextract not in path

no JExtract

we have OpenCL

  location: variable quotableComputeContextConsumer of type hat.Accelerator.QuotableComputeContextConsumer
javac ERROR /tmp/babylon/hat/hat/src/main/java/hat/ComputeContext.java  143:54 cannot find symbol
```

Maybe I am missing something. Has the build changed?

Subject: Building HAT: error, missing file?

Hi all,
    I am building HAT from the latest commit: https://github.com/openjdk/babylon/commit/82e0e551b6d8db1ccef7c00f52f7fdc786400962

It seems a file is missing.

Note that my pending branch works fine, but a few commits behind: https://github.com/jjfumero/babylon/tree/dev/examples

Getting this error:

```bash
$  java @bldr/args bld
