guest_filesystem_tests links libkernel and libc, both of which define rename_nid_postfix, so which one it binds to depends on the loader and the suite passes either way. Resolve the symbol from libkernel.prx explicitly so the export added for titles that ship their own libc.prx is actually tested. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
