* Fixes for libbeagle
This PR fixes a couple of issues with the libbeagle package.
- Use args.append('--with-cuda=%s' % self.spec['cuda'].prefix)
- Disable the default of compiling with -march=native as Spack now
inserts architecture specific flags
- Set BEAST_LIB in the beast1 package not in libbeagle.
* Use new setup_run_environment method
We'd like to use a consistent checksum scheme everywhere so that we can:
a) incorporate archive checksums into our specs and have a
consistent hashing algorithm across all specs.
b) index mirrors with a consistent type of checksum, and not one that
is dependent on how spack packages are written.
- [x] convert existing md5, sha224, sha512, sha1 checksums to sha256
- remove the old LGPL license headers from all files in Spack
- add SPDX headers to all files
- core and most packages are (Apache-2.0 OR MIT)
- a very small number of remaining packages are LGPL-2.1-only
