OpenMPI-1.6.4-GCC-4.7.2.eb had an OS dependency on libibverbs-devel,
which is a package found in RHEL-based distros and Fedora. In Debian
and Ubuntu, this package is called libibverbs-dev. In this commit I
added an OS_NAME check to make the libibverbs-devel check conditional
on running RHEL, etc. and added a check for the correct package name
on Debian.

I also added the same check into OpenMPI-1.6.4-GCC-4.6.4.eb because
it has the same dependency, and this easyconfig is used for the
goolfc-1.3.12 toolchain.

Previously, all the scipy easyconfigs listed numpy.org as the homepage
and used a copy-pasted numpy description with "Numpy" replaced with
"Scipy".

This commit changes the homepage to point to scipy.org and changes the
description to that used at the beginning of the SciPy reference manual:

"SciPy is a collection of mathematical algorithms and convenience
functions built on the Numpy extension for Python."
