<description>This update for openblas fixes the following issues:
openblas was updated from version 0.3.21 to version 0.3.25 (jsc#PED-7926, jsc#PED-7927, bsc#1221813):
- Changes in version 0.3.25:
* General:
+ Improved the error message shown on exceeding the maximum
thread count
+ Improved the code to add supplementary thread buffers in
case of overflow
+ Fixed a potential division by zero in `?ROTG`
+ Improved the `?MATCOPY` functions to accept zero-sized rows or
columns
+ Corrected empty prototypes in function declarations

builds with clang&gfortran
+ imported the following changes from the upcoming release
3.12 of Reference-LAPACK: LAPACK PR 900, LAPACK PR 904,
LAPACK PR 907, LAPACK PR 909, LAPACK PR 926, LAPACK PR 927,

- Changes in version 0.3.24:

is too small
+ Updated `?NRM2` to support negative increment values (as
introduced in release 3.10.0 of the Reference BLAS)

in release 3.10.0 of the Reference BLAS
+ Fixed OpenMP builds with CLANG for the case where libomp is
not in a standard location
+ Fixed a potential overwrite of unrelated memory during
thread initialisation on startup
+ Fixed a potential integer overflow in the multithreading
threshold for `?SYMM`/`?SYRK`
+ Fixed build of the LAPACKE interfaces for the LAPACK 3.11.0
`?TRSYL` functions added in 0.3.22
+ Applied additions and corrections from the development
branch of Reference-LAPACK:

functions (from Reference-LAPACK PR 885)

(Reference-LAPACK PR 832)

- Added a quick return from `SLARUV`/`DLARUV` for N < 1
(Reference-LAPACK PR 837)
- Updated function descriptions in LAPACK `?GEGS`/`?GEGV`
(Reference-LAPACK PR 831)
- Improved algorithm description in `?GELSY`
(Reference-LAPACK PR 833)
