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.

Dear Samuel Martin,

Any reason why we don't automatically enable blas/lapack support when
available? Also, I'd prefer to have the optional blas/lapack support
available as a separate patch from the package addition itself, so that
python-numpy can be applied independently from blas/lapack.

Thanks,

Thomas
