[yocto] [PATCH] nativesdk-qt4-tools: fix build issues with libQtDBus and libQt3Support

[Olivier Sobrie]

The libQtDBus requires libQtXml at link time otherwise it fails with
the following error:

  x86_64-pokysdk-linux-g++ --sysroot=/home/build/dev/yocto/build/tmp/sysroots/x86_64-nativesdk-pokysdk-linux -Wl,-O1 -fno-exceptions -Wl,--no-undefined -Wl,-O1 -Wl,-rpath,/opt/poky-oso/2.2/sysroots/x86_64
  /home/build/dev/yocto/build/tmp/sysroots/x86_64-linux/usr/libexec/x86_64-pokysdk-linux/gcc/x86_64-pokysdk-linux/6.2.0ld: cannot find -lQtXml
  collect2: error: ld returned 1 exit status
  make: *** [../../lib/libQtDBus.so.4.8.7] Error 1

The libQt3Support requires libQtGui and libQtNetwork at link time
otherwise it fails similarly with the following error:

  x86_64-pokysdk-linux-g++ --sysroot=/home/build/dev/yocto/build/tmp/sysroots/x86_64-nativesdk-pokysdk-linux -Wl,-O1 -fno-exceptions -Wl,--no-undefined -Wl,-O1 -Wl,-rpath,/opt/poky-oso/2.2/sysroots/x86_64
  /home/build/dev/yocto/build/tmp/sysroots/x86_64-linux/usr/libexec/x86_64-pokysdk-linux/gcc/x86_64-pokysdk-linux/6.2.0/ld: cannot find -lQtGui
  /home/build/dev/yocto/build/tmp/sysroots/x86_64-linux/usr/libexec/x86_64-pokysdk-linux/gcc/x86_64-pokysdk-linux/6.2.0/ld: cannot find -lQtNetwork
  collect2: error: ld returned 1 exit status
  make: *** [../../lib/libQt3Support.so.4.8.7] Error 1

This patch ensures that libQtXml is build before libQtDBus and that
both libQtGui and libQtNetwork are built before libQt3Support.

The build issues happen when building a SDK with the command
"bitbake meta-toolchain-qt".
