mumps_5_2_1-gnu-openmpi4-hpc-5.2.1-bp153.3.8

- Disable openmpi4 builds for SLE/Leap < 15.3.

- Change 'Requires:' to other HPC packages to %requires_eq to depend
  on the exact version. This should take care of HPC packages ignoring
  proper ABI versioning.

- Add build support for gcc10 to HPC build (bsc#1174439).
  * Remove explicit build dependency for libgomp1.
  * Add missing compiler versions to openblas and scalapack
    build dependencies.
- Add build support for openmpi4.

- With gcc10, some fortran code started failing to build -
  add compiler option -std=legacy to fix (bsc#1173549).

- Add macros to handle building of openmpi1 flavors for serial
  builds as well (bsc#1172345).

- Set %mpi_ver for scotch-openmpi
- Remove requires for libblacs from HPC builds which is not
  required there.
- Add openmpi3 non-HPC build flavor.
- Remove libblacs as explicit dependency for HPC build. BLACS
  is part of scalapack.

- Add support for gcc7 builds for HPC.
- Add support for gcc8 and gcc9 builds for HPC (jsc#SLE-7766 &
  jsc#SLE-8604).

- Disable openmpi1 builds for SLE/Leap > 15.1.
- Enable openmpi3 builds for Leap and SLE > 15.1 (jsc#SLE-7773).

- Reflect renaming of openmpi packages to openmpi1 in Tumbleweed,
  fixes unresolvable packages.

- Update Source0, file is gz and not bzip2
- Use -ffat-lto-objects to provide proper static library.

- Update to version 5.2.1 (jsc#SLE-9939)
  * See ChangeLog file or at http://mumps.enseeiht.fr/index.php?page=dwnld
- Refresh patch:
  * Makefiles-Serialize-libseq-libplat-mommond_mod-for-parallel-builds.patch
- Install the new binaries provided with the examples.

- Add BuildRequires libopenblas-gnu-hpc >=  0.3.6 for hpc to  avoid
  to build when openblas library not available (ppc64)

- added version flavor to scotch-openmpi[23] (bsc#1131426)

- Use -Wl,--whole-archive .. -Wl,--no-whole-archive instead of unpacking
  static library to build a shared library.
- Add dependency to gcc-gfortran to non-HPC build of devel package.

- Makefiles-Serialize-libseq-libplat-mommond_mod-for-parallel-builds.patch
  * Add missing dependency to serialize sub-builds.

- Changed requirements for openmpi (non-hpc) version
  %%mpi-ver -> %%mpi-ext: openmpi1 flavors omit the version number.

- Add conflicts between scotch and non-scotch flavors of example
  packages.

- Ship header files with devel package for each HPC build (bsc#1125551).

- Update RPM groups.

- Add explicit Requires: for matching libblacs2-* to non-HPC library package
