[petsc-users] reproducibility

[Satish Balay]

The commits match v3.15.0-794-g4bf14ff56a

So in the repo that gave  v3.15.0-792-gacb395f  in the log - configure was run with an earlier snapshot

Best to rerun configure [and build] to have the correct hash string [of the commit] encoded in the library.
