A portable compile cache is meant to be reused wherever the same module layout is found, which includes being generated once (at build time, say) and shipped read-only with an application for whoever runs it. On platforms with uids the cache subdirectory is suffixed with the uid of the user who created it, so such a cache is only ever found by that one user. Omit the suffix in portable mode: a user who cannot write to the directory still reads it, and a failed write is only a cache miss.
