There's a merged pull request on the void-packages repository

openblas: choose generic target for x86 and x86_64.
https://github.com/void-linux/void-packages/pull/29645

Description:
The current template uses DYNAMIC_ARCH=1 to get multiple versions of some
functions to support different cpus. However, it will pick up the cpu it was
compiled in as a minimum requirement for the common code.

Adding TARGET=GENERIC fixes this, now the common code is compiled for a generic cpu.

See #29604 and https://github.com/xianyi/OpenBLAS/issues/3139.

When skipping CI, uncomment and fill out the following section.
Note: for builds that are likely to complete in less than 2 hours, it is not
