Accept system openblas 0.3.23 and newer (needed for archlinux)

[remyoudompheng]

📚 Description

The configure script was updated to reject openblas 0.3.22 but the test introduced in #35377 is too restrictive and excludes openblas 0.3.23.
This patch addresses the issue for the non pkg-config case (currently on Archlinux, openblas.pc has no version number and pkg-config is not used in the configure process).

I'm not sure how to handle the pkg-config case (the syntax is not very flexible).

Marking this as critical because on archlinux, we neither accept the system openblas nor are able to build our own openblas (#34899)

I'm on Archlinux and facing the same issue as described. I previously built sage successfully from source when the OpenBLAS version was 0.3.21 and the OpenBLAS was built from https://aur.archlinux.org/packages/openblas-lapack .
Now when I do the same now, the OpenBLAS package isn't detected and the built of OpenBLAS (0.2.23) fails as mentioned in the above comments. Looking at the logs doesn't provide anything helpful at all. Also, the AUR package doesn't build currently on my system as I've mentioned here - aur/openblas-lapack#comment-912197 by prs.

What can be a workaround at the present?

After many trials, I went with the official repository packages for openblas and lapack and was able to successfully build sage after cleaning the previous build files and everything seems to be working fine now. Should I also try using this method? Note that I'm unable to build the 0.3.23 package for OpenBLAS as mentioned above so this was the only resort and openblas didn't install through the sage build. Am I missing something?

(This was started before your comment so I waited for this build).

official repository packages for openblas and lapack

official - as your OS (Archlinux) official, or upstream (OpenBLAS) official?

I'm referring to the Archlinux package repository here. The upstream project only provides official binary packages for Windows.

OK then - this PR is exactly for this purpose.
