To be honest, I am not sure why add this include. After build it is 
harmless, so I didn't want to modify it because I think LFS is trustable.

Its matter of understanding the change and may be explaining a bit better what it fixes and make the patch better for upstream too so try to build it without this include added and see if you get some warnings/errors that it fixes and then add that information to patch header.

It is no warning shows without the include patch. But the patch is merged.
