Distro to install on a PowerPC G4 after Debian dropped 32-bit PPC support

Debian dropped support for my PowerPC CPU. For this reason my security updates are now no longer granted and I am clearly not happy about that. Is there any distro out there that supports PowerPC and provides an automatic compilation of updates on my PC? In my hopes I can get a distro that in the moment I run something like apt upgrade downloads the packages from source, compiles locally and install. Is there such a thing?
