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
