scalapack-openmpi5-2.2.0-bp160.1.5

- Disable and remove support of gnu-hpc build flavours (bsc#1239982)
- openmpi5 is not available on 32b systems
- Switch default openmpi to openmpi4 to openmpi5

- Update to version 2.2.0:
  * Feature: Allow compilation in ILP64 mode
  * (gh#Reference-ScaLAPACK/scalapack#19).  Bugs fixed:
  - Use pointer macro to prevent integer overflow
    (gh#Reference-ScaLAPACK/scalapack#16).
  - Fix argument mismatches for implicitly defined functions
    (for gcc-10+ compatibility)
    (gh#Reference-ScaLAPACK/scalapack#26).
  - No memory leaks on blacs_exit
    (gh#Reference-ScaLAPACK/scalapack#37).
- Add `-Wno-error=implicit-function-declaration` to work around
  non-prototyped functions (gh#Reference-ScaLAPACK/scalapack#81).

- Enable openmpi5 and gnu-hpc-openmpi5 flavours.

- Disable HPC flavors on i586

- Drop support for obsolete openmpi[123]
- Prepare support for openmpi5

- 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.

- Fix build for non-HPC packages: do not build BLACS headers for
  multiple flavors (boo#1178116).

- Add build support for gcc10 to HPC build (bsc#1174439).

- Add openmpi4 spport (provided by Alin M Elena)
- Replace -fallow-argument-mismatch by -std=legacy

- Add compiler flag -fallow-argument-mismatch to allow build with
  gcc10.
