gnu: openblas: Add support for older x86 processors.
Fixes <https://issues.guix.gnu.org/51452>.
* gnu/packages/maths.scm (openblas)[make-flags]: Make the x86_64, i686,
powerpc64le and aarch64 architectures share the same flags; this causes the
DYNAMIC_OLDER=1 to be added for all of them and TARGET=GENERIC to be added
for
the x86_64 and i686 architectures.
