Auto merge of #71931 - alexcrichton:reproducible-macos, r=eddyb
Export ZERO_AR_DATE for macos linker invocations This commit attempts to improve reproducibility of builds on macOS by exporting the `ZERO_AR_DATE=1` environment variable for all invocations of the linker. While it looks like this env var is targeted at just the `ar` command (which does actually read this) it appears that recent-ish versions of the linker *also* read this environment variable. This env var forces the linker to set a deterministic zero value for the mtime in the N_OSO field of the object file. Currently it's believe that older versions of the linker will simply ignore this env var, while newer versions will read it and produce a deterministic output for compilations with debuginfo. Closes #47086 Closes #66568
