commit: https://git.buildroot.net/buildroot/commit/?id=27d22296927d7e4ec0965f2bdaa272b1e8ea15e7
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master
Some packages build C++ 32bits host-tools and need the g++-multilib to
be installed on the build machine. As example, qt5webengine builds a C++
host-tool when target is 32bits.
Add the check for g++-multilib to the dependencies script; and update
the Dockerfile to install g++-multilib package.
