Remove configure check LOG1P_DROPS_ZERO_SIGN. (GH-9193)
It is unused. <!-- Thanks for your contribution! Please read this comment in its entirety. It's quite important. # Pull Request title It should be in the following format: ``` bpo-NNNN: Summary of the changes made ``` Where: bpo-NNNN refers to the issue number in the https://bugs.python.org. Most PRs will require an issue number. Trivial changes, like fixing a typo, do not need an issue. # Backport Pull Request title If this is a backport PR (PR made against branches other than `master`), please ensure that the PR title is in the following format: ``` [X.Y] <title from the original PR> (GH-NNNN) ``` Where: [X.Y] is the branch name, e.g. [3.6]. GH-NNNN refers to the PR number from `master`. -->
