Previously, standalone applications were compiled with gcc flags that produced relocatable executables on the PowerPC architecture (eg with the -mrelocatable and -fPIC flags). There's no reason for these applications to be fully relocatable at this time since no relocation fixups are performed on standalone applications.
This didn't work for me. The entry point for my application in 401b4. Here's the build output:
