%%% src_install
The following code from original LFS is not executed:

\begin{verbatim}
chown -v -R root:root \
    /usr/lib/gcc/*linux-gnu/10.2.0/include{,-fixed}
\end{verbatim}

We do not need that, as all built files are user-owned by now.
At the installation stage all files will automatically obtain root owner.
