[Buildroot] [PATCH 07/11] python-numpy: new package

[Samuel Martin]

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.
