commit: https://git.buildroot.net/buildroot/commit/?id=615e2edc2ae8351519448d1965f0c4eec4e793b1
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master
A patch was added to the Linux kernel in 5.1.0-rc3 which adds a
requirement that the host build environment include pkg-config. Add the
correct host-pkgconf dependency and environment variables to ensure
Linux picks up the correct libraries.
Move the existing LINUX_MAKE_ENV assignment earlier, to simplify the
append-assignment in the libelf conditional block.
Fixes: #11761
