The last commit (be25d3413b432b56e9789eae55920f1862008911) should fix the problem. I made a build with the following configuration:

./configure \
        --with-toolchain-type=clang \
        --disable-jvm-feature-shenandoahgc \
        --disable-jvm-feature-zero \
        --disable-jvm-feature-zgc \
        --disable-jvm-feature-g1gc \
        --disable-jvm-feature-parallelgc \
        --disable-jvm-feature-epsilongc

and then I ran the script on this build to extract the [inclusions count](https://github.com/user-attachments/files/21692915/inclusions_count.txt). This could be included in the README file attached to this PR.
