+Subject: [PATCH] configure.ac: make mysql support cross-compile friendly
+
+When cross-compiling mysql_config shouldn't be expected to be in PATH
+since normally this would point to distribution mysql rather than cross,
+which can be of a totally different architecture.
+
+Change it so we can use ac_cv_prog_MYSQL_CONFIG to point to the real one.
