Hervé, All,
On 2021-08-17 10:39 +0200, Herve Codina spake thusly:
> Without this patch, a make <pkg>_rebuild detects overwrites. Indeed, in
> target_finalize steps some modifications are done on installed files (ie
> strip or TARGET_FINALIZE_HOOKS for instance).
>
> In order to avoid these modifications seen from per-package {TARGET,HOST}_DIR
> and so been analyzed as some overwrites, global {TARGET,HOST}_DIR is built
> using a full copy of the involved per-package files instead of hardlinks.

I was about to apply that one, because it does not look like it
(semantically) depends on the previous patches, but of course it does
not apply cleanly... I found it too dangerous to apply and tweak locally
without further consideration. So it follows the fate of the rest of the
series: marked Changes Requested.
