Bug#667341: qmf: ftbfs with GCC-4.7

[Matthias Klose <doko@debian.org>]

here is a patch to fix the GCC 4.7 issue. However the build fails later with

g++ -m64 -Wl,-O1 -o build/tst_qmailthread tst_qmailthread.o
-L/usr/lib/x86_64-linux-gnu -L../../src/libraries/qmfclient/build -lqmfclient
-lQtTest -lQtCore -lpthread
tst_qmailthread.o: In function `tst_qmailthread::test_threadKeys()':
tst_qmailthread.cpp:(.text+0x559b): undefined reference to `void
QMailThreadSortKey::deserialize<QDataStream>(QDataStream&)'
collect2: error: ld returned 1 exit status
make[3]: *** [build/tst_qmailthread] Error 1
make[3]: Leaving directory
