Because of issue 22822, the dmd.root.file module is broken on PPC. The `st_size` field it reads is actually at the offset of padding, so it thinks that every file has a size of 0, meaning nothing gets read into the parser, and nothing written out by the compiler.
We can fix druntime, but all previous releases are still broken, so we need to "workaround" this issue in the compiler front-end itself by providing a stub implementation of stat_t to use on linux/PPC only.
