Fix bisection comes up with the following kernel commit:

    commit 80463f1b7bf9f822fd3495139bcf3ef254fdca10
    Author: Masahiro Yamada <yamada.masahiro@socionext.com>
    Date:   Fri Sep 14 15:33:23 2018 +0900
    
        kbuild: add --include-dir flag only for out-of-tree build

But only for in-tree builds.  Out-of-tree builds need:

    commit 3812b8c5c5d527239ac015f1f2c7654da7fcfbba
    Author: Masahiro Yamada <yamada.masahiro@socionext.com>
    Date:   Fri Feb 22 16:40:07 2019 +0900

        kbuild: make -r/-R effective in top Makefile for old Make versions

Masahiro, what dependencies (if any) do the above two commits have in order to
be backported to 4.19 and 4.14?
