@mreid-tt If you don't mind, I will create a dedicated PR for c-ares update
it is an issue in #6127 too (build of rutorrent) and needs an older version for OLD_PPC_ARCHS

Sure @hgy59 not a problem. I'll remove the c-ares code and wait until you merge so I can re-base.

Seems we are unable to build due to this bug: transmission/transmission#6873.

@mreid-tt I have created a source archive that includes the submodules and added it to synocommunity releases in https://github.com/SynoCommunity/spksrc/releases/tag/transmission

I first tried to enhance the spksrc framework to use git repositories with submodules, but since the PKG_DOWNLOAD_METHOD=git creates different hashes (digests file) when recreating the archive with unmodified content, this is not a solution.

I also provided the script to create the archive for documentation and content validation.

@hgy59 appreciate your workaround to this issue. I'll begin package testing and then move to publishing.
