Subject: ATLAS and Scipy working on GNU/Linux

Numpy needs ATLAS as shared libraries. So we also need to build Python with
shared libraries.  We also need to define site.cfg for numpy and scipy so we
define a master template:
`reproduce/config/pipeline/dependency-numpy-scipy.cfg'

Also `Openssl' did not have rpath so we added with this commit.
