 Notes:
-- If --bin-dir is omitted, 'fastrpc_test' must be on PATH or in known fallback paths.
-- Default assets location prefers \$BINDIR/linux (so /usr/bin/linux in your layout).
+- Default binary path is /usr/bin/fastrpc_test.
+- /bin/fastrpc_test is used ONLY if ALLOW_BIN_FASTRPC=1 or you pass --bin-dir /bin.
+- Default assets location prefers \$BINDIR/linux (so /usr/bin/linux).
 - If --arch is omitted, the -a flag is not passed at all.
