[Buildroot] [PATCH v3 10/16] Makefile: breaks hardlinks in global {TARGET, HOST}_DIR on per-package build

kernel build + files below scripts/ (unless maintained elsewhere), the rest · Maintainers:

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.
