Test error on 0.4 release branch

[eschnett]

After updating on the 0.4 release branch, I see this error in make -j8testall on Darwin:

Exception running test linalg/svd :

I believe this is due to #14444 and was fixed on master by #14522 . We can probably fix it on 0.4 with a smaller patch by replacing info[1] with info[].

[andreasnoack]

Why haven't we caught this in CI?

Openblas version

Bump @nalimilan your backport was buggy and it'll need to be fixed before we can do 0.4.6. Can you take a look?

[nalimilan]

Sorry for the slow reaction. #15883 fixes the failure with 0.2.16 in my tests (I wonder how I introduced it in the first place -- maybe I changed something right after testing).

[tkelman]

Should be fixed, but wouldn't mind a confirmation from anyone who was able to reproduce this.
