eigen: add C++ toolchain dependency

As said in its help text, eigen heavily uses C++ features.
So, explicit this dependency in the Config.in.

qt: add an option to install the test module

When building Qt in a minimal configuration, a couple of Qt modules
(QtNetwork, QtSql, QtTest and QtXml) are built in addition to QtCore,
so they are installed in the sysroot but they are not copied into the
target tree.

Among these modules that could be built but optionally installed, only
QtTest had no option to allow being installed in the target fs.

Thus, programs linking against QtTest would successfully build, but
would miserably fail at runtime due to this missing dependency.

So far, the only package triggering this issue is OpenCV (the highgui
module built with Qt support).

A followup patch will add this missing dependency in OpenCV using this
new option.

opencv: fix qt selection when highgui is enable

The OpenCV highgui module links against QtGui and QtTest.
The latter is built by default but was never installed.
Thanks to the previous patch on Qt, this can be rectified.

So, update the OpenCV Config.in with the missing Qt module selection.

support: mkusers: add warning when using mkpasswd from the host system

Because the mkpasswd provided by some distribution does not support all
options used in the mkusers script, mkpasswd has been integrated as a
package.

However, using a custom rootfs skeleton, the host-mkpasswd target is not
automatically built, even if some packages add users.

In this case, to help the Buildroot users understanding what happen when
the mkpasswd from the host system is used (so, might fail), mkusers now
print a warning message explaining how to solve this.
