codespell is complaining about a non-error, that isn't even part of this PR 🤷♂️ |

I think we might want to call this something like BUILD_FLAGS_REPRODUCIBLE= because -buildvcs=false is something we will also want to add, and it will also strip debug information that users might want (notably the commit id). I think it's fair to say that most of the build flags we will add for reproducibility are going to be related to removing debug information that is less reproducible...
Or maybe you don't care about the vcs information auto-added to Go binaries in the recent versions of Go?

I can see use cases both ways. My immediate preference is a flag targeted on trimpath, but if you prefer the flag as you put it, I'm fine changing it. What's your preference?

BUILD_FLAGS_REPRODUCIBLE
Can we use SOURCE_DATE_EPOCH ?

What does SDE have to do with whether or not we set trimpath?

If it is set, it is expected to be reproducible

Oh. If set, run -trimpath, else not? That does change the default from "no special var set = trimpath" to "only if special var set = trimpath", but if that's what you want, I can change this PR. Let me know.
This is being fixed in #3907 which is waiting for another LGTM. Please ignore for now. |

Cool. I'll ignore. Waiting to see if @cyphar wants me to rename it as suggested in his comment, or just leave it like this. |

@cyphar and @kolyshkin what can I do to move this ahead? |

Rebased on main now that #3907 is in. What else can I do to move this ahead? |
|
Also, whatever you did in #3907 works, as that check no longer is failing. |
|
Been a few weeks; can we get a review and a potential merge, please? |

Fixes #3906
Makes
-trimpathoptional by calling it asThe default mode is unchanged.
Comments in the Makefile make it clear that this may still be required for reproducible builds.
