Commit 09e5b3fd5672 ("Fonts: Support FONT_EXTRA_WORDS macros for built-in fonts") introduced the following error when building rpc_defconfig (only this build appears to be affected):

The .data section is discarded at link time. Reinstating acorndata_8x8 as const ensures it is still available after linking.

Shouldn't we add the const to all of them, for consistency?
The thought did cross my mind. However, I do not see any further issues which need addressing. Nor do I have any visibility into what issues may be caused by doing so. The only thing I know for sure is that this patch fixes the compile error pertained to in the commit message, and I'd like for this fix to be as atomic as possible, as it's designed to be routed through the Stable/LTS trees.
