Depends on the kind of software. POSIX compatible C requires few, if any, source changes. Code that makes direct syscalls will need more work.

It's worth pointing out that MacPorts still has a lot of modern tools and utilities working for PowerPC Macs. This is despite PowerPC Macs being 'officially' stuck on GCC 4.2 (unless you install newer... through MacPorts), ancient Mac OS X frameworks and barely any developers have a PowerPC machine at hand (because why would they).
MacPorts also mostly supports Apple silicon. It's pretty cool!
