[U-Boot] Tools build failure when libfdt-devel is installed

2 Mar 2018


      Hello,
I'm running a Fedora 27 system. When the libfdt-devel package is not
installed in the distro, U-Boot builds fine. When libfdt-devel is
installed, the build of U-Boot tools breaks badly, because it includes
headers from /usr/include/ for libfdt, instead of using only its own
internal headers.
See below the full build log. I've tried to fix it, but the way libfdt
is integrated in U-Boot is not really easy to understand, with
apparently multiple copies of it, referencing each other.
Any idea ?
