Changes v2 -> v3:
- The PRs related to the patches have all been merged. The first PR was
merged by combining the three patches into a single one. Replace all
Upstream: links with the link to the final commit.
- Add help text to the added KConfig options.
- Select external libraries for BROTLI and YAML_CONFIG options.
- Drop the host configurations. Files too.
- Always add -DBUILD_CTL=ON to HOST_DROGON_CONF_OPTS (together with
-DBUILD_TESTS=OFF and -DBUILD_EXAMPLES=OFF).
Changes v1 -> v2:
- Drop BR2_ARCH_IS_64 dependency. It has been tested on imx6ull platform.
- Add DROGON_INSTALL_STAGING
- Add 0004-Fix-building-error-for-Werror-unused-value.patch for trantor
submodule.

Hi Dario,

The drogon.hash file is missing. When running the
command "make drogon-legal-info", we can see the messages:
...
WARNING: no hash file for drogon-v1.9.11-git4.tar.gz
...
WARNING: no hash file for LICENSE
Could you add the hash file please?
Also, this package is introducing build failures. There is probably
missing dependencies.
See: https://gitlab.com/jolivain/buildroot/-/pipelines/2682597534
You can also reproduce locally with the command:
utils/test-pkg -a -p drogon
While fixing those issue, could you bump to the latest 1.9.13. This
should remove some (if not all) package patches.
Could you send an updated patch addressing those issues, please?
