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.
