Fedora packages built with 'HAVE_DTRACE' option, but there is no dpendecy on systemtap-sdt packages

the problem appears during MaxScale build attempt for Fedora 19/20:

In file included from /usr/include/mysql/private/probes_mysql.h:22:0,

                 from /usr/include/mysql/private/sql_class.h:38,

                 from query_classifier.cc:45:

/usr/include/mysql/private/probes_mysql_dtrace.h:9:21: fatal error: sys/sdt.h: No such file or directory

 #include <sys/sdt.h>

                     ^

The problem can be solved by installing "systemtap-sdt-devel" package.

The probes_mysql.h header file has the following content:

#if defined(HAVE_DTRACE) && !defined(DISABLE_DTRACE)

#include "probes_mysql_dtrace.h"

#else  /* no dtrace */

#include "probes_mysql_nodtrace.h"

#endif

it looks like HAVE_DTRACE is defined during MariaDB build and "probes_mysql_dtrace.h" is included into the build, but dependency on "systemtap-sdt-devel" is not set and "systemtap-sdt-devel" is not installed when mariadb-devel is installed.

It is possible the same happens in CentOS 7, but can't test now due to lack of libmysqld.a in CentOS7 packages.
