+Subject: [PATCH] build/ax_lua.m4: fix cross-compilation
+
+Don't try to "find" and "fix" the script and module directories when
+cross-compiling as this will give unexpected results such as using
+${prefix}/lfs/hdd_v1/rc-buildroot-test/scripts/instance-0/output-1/host/usr/share/lua/5.3
+instead of
+${prefix}/share/lua/5.3
+if the host machine root directory is /usr
+
+Fixes:
+ - http://autobuild.buildroot.org/results/09fa6dd9844d6d4694801ec59434dad7a56bf290
