exim: get rid of the convert the custom config file boolean knob

The current implementation causes troubles with the autobuilders when they
set BR2_PACKAGE_EXIM_CUSTOM_CONFIG=y, because in these cases
BR2_PACKAGE_EXIM_CUSTOM_CONFIG_FILE is empty, and this is a configuration
error.

Solve the problem by entirely reomving the BR2_PACKAGE_EXIM_CUSTOM_CONFIG
boolean knob. Activation of the custon configuration file is now detected by
the fact that BR2_PACKAGE_EXIM_CUSTOM_CONFIG_FILE is non-empty.

Fixes:

qt5: Add an option to select default platform

Whithout this path, default platform is automaticaly set (generally
set to "eglfs" as defined in
qt5base/mkspecs/devices/common/linux_device_pre.conf:1). This choice
is not always what the user would like. Thus, user have to manually
appends "-platform <BACKEND>" to command line when running any qt5
application.

This patch allows user to choose default platform explicitly.

[Thomas: slightly improve Config.in help text, from the suggestions
given by Yann E. Morin.]

pkg-python: add staging installation support

python-numpy needs to be installed to the staging directory, since it
also installs some header files. Therefore, this commit extends the
Python package infrastructure to support staging installation.

python-numpy: new package

This patch add NumPy package for python.

Since Fortran support has been deprecated in Buildroot since the 2013.11
release, and because most of the external toolchains do not provide a
Fortran compiler, it is necessary to explicity disable Fortran compiler
to avoid catching the one from the host system if any.

We also need to fill a site.cfg file to tell NumPy build-system where
it should looking for BLAS and LAPACK libraries.

Some packages may include headers provided by python-numpy package, so
python-numpy is installed to the staging directory.

[Thomas:
 - add dependency in Config.in to take into account fenv.h
   requirement, suggested by Yann E. Morin.
 - modified to use the staging installation logic in the python
   package infrastructure.]

 - Properly format the "libraries" entry in site.cfg as outlined in
   the example site.cfg file: the list of libraries should be

opencv: bump to version 2.4.8

This patch bumps OpenCV version and address the minimal set of change to
get the new version building correctly:
- update the download location;
- force Qt version to Qt 4 when support is enabled;
- naively fix the v4l support.

However, it does not address a couple improvements, among these:
- jasper support;
- python/numpy support;
- Qt4 and Qt5 support (since the 2.4.6 release), so only Qt4 support is
  supported in this patch;
- optional libv4l dependency (since 2.4.7 release);
- etc.
These will be addressed in followup patches.
