Add a bit of explanations in the commit log, especially given the
following...

So, we are dropping all the arc specific versions for the toolchain
components, but we eventually introduce a defconfig that relies on an
arc specific version of qemu, that we do not even package in Buildroot,
so that users can't even enable host-qemu in Buildroot.
That is a bit sad...
What is the rationale for introducing this defconfig, then?
Regards,
Yann E. MORIN.
