databases/mysql-connector-odbc causes segmentaion fault in libmysql in
mysql_get_character_set_info()

i think the problem is caused by my_thread_global_init which is present in
libmysqlient.so and libmyodbc5a and causing a split brain init 
odbc drv call mysql_init which calls mysql_server_init which calls
my_thread_global_init and the odbc ver is executed and the static
my_thread_global_init_done in lmysqlclient is not set
this cause silent failures of mysql_init and in the end segv

the fix is to link libmysqlclient(_r).a with the odbc driver
CMAKE_ARGS=     -DWITH_UNIXODBC=1 -DDISABLE_GUI=1
-DMYSQLCLIENT_STATIC_LINKING=1
