[OE-core] [PATCH 1/6] qt4: fix compilation issue

[nitin.a.kamble at intel.com]

From: Nitin A Kamble <nitin.a.kamble at intel.com>

gcc 4.7 uncovers a type mismatch in the code. And this commit fixes the issue:

| /srv/home/nitin/builds/build-gcc47/tmp/sysroots/qemux86/usr/include/glib-2.0/glib/gthread.h:58:7: error: 'union' tag used in naming 'struct _GMutex' [-Werror=permissive]
| In file included from ./wtf/Platform.h:1217:0,
|                  from ./config.h:30,
|                  from wtf/gobject/GOwnPtr.cpp:19:
| wtf/gobject/GTypedefs.h:55:16: note: 'struct _GMutex' was previously declared here
NOTE: package qt4-x11-free-4.8.1-r41.1: task do_compile: Failed
