This patch adds -Wno-typedef-redefinition compile option

On osx yosemite, compiling gstreamer with master of glib causes following
warning.


In file included from gstnetclientclock.c:58:
In file included from ./gstnettimepacket.h:25:
In file included from /mypath/install/include/glib-2.0/gio/gio.h:163:
/mypath/install/include/glib-2.0/gio/glistmodel.h:36:21: error: 
      redefinition of typedef 'GListModel' is a C11 feature
      [-Werror,-Wtypedef-redefinition]
G_DECLARE_INTERFACE(GListModel, g_list_model, G, LIST_MODEL, GObject)


Here is my gcc version information;

$ gcc --version
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr
--with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 6.0 (clang-600.0.56) (based on LLVM 3.5svn)
Target: x86_64-apple-darwin14.1.0
Thread model: posix


This warning is caused by including gio/gio.h.

But, as the warning says, redefinition of typedef is valid in C11 and no need
to stop compiling for this.

I attached a patch to add -Wno-typedef-redefinition compile option to
configure.
