[Buildroot] [PATCH 4/6] scons: force host-python dependency to be python2

[Yann E. MORIN]

Samuel, All,

On 2014-03-05 23:04 +0100, Samuel Martin spake thusly:
> Scons build-system needs python2 as interpreter (it does not support
> python3 yet).
> 
> So, we need to force the host dependency to get the python2 interperter
> built and available in the host tree to be able to build host-scons
> itself and to build scons-based packages, whatever is the python
> interpreter for the target.
> 
> This patch also makes sure scons will in be called using the right
> python interpreter when invoked via $(SCONS).
> 
> Fixes:

If the variable is renamed, my reviewed-by will still be valid.
