Say hello to Qt for Native Client.

This commits adds build system to support for the native 
client compiler (x86-only for now), sets up global defines,
and adds compile fixes for QtCore and QtGui.

Details:

* Add mkspecs for linux-nacl-g++ and macx-nacl-c++
* Add nacl configure option
* Add qconfig-minimal-system-dependencies.h
* Define Q_OS_NACL in qglobal.h
* Add qnacalunimplemented.h/cpp with POSIX stubs.
* .pro file changes for cross-compiling on Mac

+
+    There are two main classes of functions:
+
+    - Fuctions that are called but can have no effect:
+    For these we simply give an empty implementation
+
+    - Functions that are referenced in the source code, but
+    is not/must not be called at run-time:
+    These we either leave undefined or implement with a
