- some lint clean up
- set up wget dependency (towards enabling "make test")
- OMP_NUM_THREADS=1 during check (towards enabling "make test")
- enable all arithmetics
- correctly builds the master branch:
guix environment --pure --ad-hoc qr_mumps --with-git-url=qr_mumps=/my/path/to/git/clone/of/qr_mumps/ --with-branch=qr_mumps=master

* non-free/cuda.scm (cuda): Dowgrade to 10.2.

* non-free/cuda.scm (cuda-10.2): New variable.

* inria/tainted/storm.scm (starpu+cuda)[arguments]: Pass "--disable-opencl".

add pipelines for 'mumps-mkl', 'mumps-mkl-metis', 'mumps-mkl-openmpi', 'mumps-mkl-metis-openmpi' and 'pastix-5-mkl' packages.

* README.md (How does it work?): Update.

* non-free/cuda.scm (cuda): Change to CUDA-11.0.
* inria/tainted/storm.scm (starpu+cuda)[native-inputs]: Remove
NO-FLOAT128.
[build-system]: Remove.

* non-free/cuda.scm (cuda-11.0): New variable.
(no-float128)[description]: Mention CUDA 8.0.

- same as chameleon
- plus otherwise the package transformation --with-input=openmpi=nmad was not effective

inria/tainted/hiepacs.scm: replace hdf5 by hdf5-parallel-openmpi for parallel MPI versions of fmr and diodon

* inria/tainted/storm.scm (gfortran-sans-libstdc++): New variable.
(starpu+cuda)[native-inputs]: Use it instead of GFORTRAN.

Previously, both GCC 7 and GCC 5 would be among the inputs.  Thus, both
libstdc++ versions would show up in CPLUS_INCLUDE_PATH, followed by
libc.  Consequently, #include_next logic would fail: <math.h> from
GCC 7's libstdc++ would be picked up instead of <math.h> from libc.  The
end result was a build failure like this:

  In file included from /gnu/store/…-gcc-7.5.0/include/c++/stdlib.h:36:0,
		   from ../include/starpu.h:22,
		   from core/simgrid_cpp.cpp:19:
  /gnu/store/6wn346cbw1mh6264v426pwj2klgvxr0z-gcc-5.5.0/include/c++/cstdlib:118:11: error: ‘::div_t’ has not been declared
     using ::div_t;
	     ^

Notice the mixture of GCC 7 and GCC 5 libstdc++ headers.

The regression is presumably a consequence of Guix commit
2073b55e6b964cb8ca15e8c74cb32dac00f05f0d, which switched by to
CPLUS_INCLUDE_PATH & co. instead of CPATH.

* inria/tainted/storm.scm (gnu-build-system-with-compiler): New
procedure.
(starpu+cuda)[build-system]: New field.
[native-inputs]: Remove GCC-5.

gitlab-ci: add missing tests of some hiepacs packages
