* Update and simplify julia package
The current Spack Julia package potentially installs a few julia
packages, with the installation being controlled by variants. There are
a couple of problems with this.
First, Julia handles packages very differently from systems such as R
and Python. Julia requires write access to the repository directories in
order for user installs of packages to work. If spack installs julia
packages then there will be a repository, DEPOT_PATH, in the
installation directory. If spack is used on an individual basis this
would work but would mean that package data is written to the spack
installation directory after installation. If spack is used to provide
packages for end users then user installs of julia packages will fail
due to lack of write access to the repository in the installation
directory. It seems best for spack to just install julia without any
julia packages, and drop the configuration for those packages.
Second, having spack install package as variants seems to be counter to
how spack works for other extendable systems, like R and Python. Julia
should be an extendable package in spack but it is not clear how to make
that work. As pointed out above, installing user packages requires write
access to the julia repositories, including the one in the install
directory. Essentially, a user package installation will try to update
metadata for *all* julia repositories. Furthermore, each of those
repositories, assuming one per package with spack, would need to have
the Project.toml files merged to present the package stack to julia.
Again, it seems best for spack to just install julia itself and not try
to install julia packages, at least at this time. A good discussion on
this can be found at

This PR does the following:
- adds versions 1.2.0 and 1.3.1
- removes variants that correspond to julia packages
- changes python to build dependency as it seems to only be needed for
LLVM
- the new versions can use Python-3
- removes dependencies for packages
- adds a conflict statement for Intel compiler, with comment
- add a setup_build_environment method to find GCC libraries
- make formatting consistent
- adds JULIA_CPU_TARGET option to correspond with target to help with
running julia image on hardware older than build host
- added intel build options, for when they can be used
- removed code for installing packages
- removed code for julia config that was needed for packages
Note that versions below 0.5.1 fail to build, with or without these
changes. It is not clear why that is.
* Update var/spack/repos/builtin/packages/julia/package.py
Yes, need to use correct grammar even in the midst of numbers and symbols. Good catch!

* More cleanup of Julia package
This commit does more cleanup and sets more constraints.
- Removed release-0.4 and release-0.5. I am not sure if those are
actually useful but they are quite old and there are released versions
from the same timeframe.
- Remove the binutils variant.
- Made cmake a build dependency for versions >= 1.
- Added git as a dependency for @master.
- Limit curl dependency to released versions.
- Do not use external curl for master. When I checked, using the
external version failed but the internal curl worked.
- Versions <= 0.5.0 need an older version of openssl.
- Set conflicts directive for cxx variant.
- Added conflicts directive for needing +mkl with Intel compiler.
- Removed configuration settings as these prevented julia from working
properly in all cases that I looked at.
* Fix flake8 error
Remove 'import sys' that is no longer used.
* More dependency tweaks
This commit sets further version constraints on dependencies. It really
looks like julia requires its internal dependencies more over time.
- curl only up to 0.5.0
- openssl only up to 0.5.0
- override with system curl up to version 0.5.0
* Fix spec for curl certs
Only depending on curl through 0.5.0.
