superenv: help Autotools with 10.13 SDK on 10.12

Browse Source 
The GNU Autotools tests for whether futimens and utimensat are available
reliably come to incorrect conclusions on 10.12 with the 10.13 SDK in
Xcode 9. This overrides its decisions by forcing the right answer
in superenv using ac_cv_func_* environment variables and setting them to
"no" on 10.12.
