gnumake: disable subsecond mtime on darwin

gnumake can support subsecond mtimes if it is available. But Darwin
doesn’t support setting subsecond mtimes until 10.13! So we can just
disable this check to avoid the issue where most of our built tools
use seconds but make uses nanoseconds. Might fix some parallel issues
along the way.

Fixes #51221
