[Buildroot] [PATCH v3 3/4] Makefile: add TARGET_CLEAR_RPATH_HOOK to TARGET_FINALIZE_HOOKS

[Samuel Martin]

This patch introduces the TARGET_CLEAR_RPATH_HOOK hook fixing the ELF
files' RPATH of the host tree (excluding the sysroot).

After running this hook, the RPATH from any target ELF files is empty.
