This would be a <code style="font-size: 90%; color: #18171d; word-wrap: break-word; background-color: #ececef; border-radius: .25rem; font-weight: inherit; overflow-wrap: break-word; white-space: break-spaces; font-family: "GitLab Mono", "JetBrains Mono", "Menlo", "DejaVu Sans Mono", "Liberation Mono", "Consolas", "Ubuntu Mono", "Courier New", "andale mono", "lucida console", monospace; font-variant-ligatures: none; word-break: keep-all; padding: 0.125rem 0.25rem;">%define</code> checked in the common GCC build recipe as bring defined to catch all newlib hash instances.

<p dir="auto" style="color: #3a383f; margin: 0 0 1rem;" align="initial">The newlib tag is a date in a neutral format. The date just needs to be later than date being replaced. I suggest it is the date the change to the newlib hash is made.</p>
