No, there is no such statement.

There is an agreement that files with GPL should be GPLv2+
(not only GPLv2), but files may also use other free licenses.

In file LICENSE, it is said that QEMU as a whole is released
under the GNU General Public License.

Some files are copied from Linux and therefore must use
the Linux license (usually GPLv2).

syscall_defs.h might be a copy from Linux (=> GPLv2).
If not, the default rule from LICENSE could be applied (=> GPL).

Stefan
