Built-Using to record gnu-efi, libc, compilers, etc. used to build shim?
I'm preparing a shim 12 upload for Ubuntu and testing upstream work; I was wondering, could we make use of Built-Using to somehow record the versions of compilers, gnu-efi, etc. that were used to build a particular shim binary package?
Done right it would beat visually parsing build logs to collate that information when we get to the time of sending a review request to the shim-review@ mailing list, and make it easy to figure out whether shim needs to be rebuilt, re-signed, etc. in the event of a big issue with the toolchain.
