+Subject: [PATCH] configure.ac: fix cross-compilation with lua
+
+lua integer size is detected through AC_RUN_IFELSE since
+https://github.com/OISF/suricata/commit/2abcd5d27f29ca37ae31108cc0ea0143fa25d0a1
+
+This breaks cross-compilation and is needed only for rust so disable it
+if rust is not wanted
