- add cuda variant, enabled by default, but conflicting with
  strumpack@:3.9.999
- add zfp variant, enabled by default, but conflicting with

- update minimum CMake version to 3.11
- for version 4.0.0:, do not use mpi wrappers. v4.0.0 uses CMake
  MPI targets
- for version 4.0.0, add dependency on butterflypack@1.2.0:
- remove versions 3.1.0 and older
- make parmetis variant True by default
- add TODO for slate variant (spack package not ready yet)

While I believe there must have been a reason to restrict libtool to <=
2.4.2, adios compiles just fine with libtool 2.4.6 for me.

In fact, without this change, I'm getting this error:

libtool: Version mismatch error.  This is libtool 2.4.6, but the
libtool: definition of this LT_INIT comes from libtool 2.4.2.
libtool: You should recreate aclocal.m4 with macros from libtool 2.4.6

This doesn't make much sense, since spack did build libtool@2.4.2 as a
dependency, and was supposedly trying to use it. My guess is that on
this system (NERSC's cori) the system libtool in /usr/bin, which is
2.4.6 somehow got picked up partially.

Semi-recently the lua spackage was updated to explicitly add libtinfow
to the lua build line. Ncurses provides this but only when the +termlib
variant is enabled

* make_package_relative: relocate rpaths on cray

* relocate_package: relocate rpaths on cray

* platforms: add `binary_formats` property

We need to know which binary formats are supported on a platform so we
know which types of relocations to try. This adds a list of binary
formats to the platform and removes a bunch of special cases from
`binary_distribution.py`.
