The commit log was missing a reference to the autobuilder failure that
this commit fixes, so I've added it and applied to master.

I looked at the discussion with Yann, and yes some more elaborate
solution could perhaps be introduced to avoid the hook. But for now the
work done on autoconf allows to avoid the hook in most situations,
except when autoconf-archive is needed, which is only a small minority
of our packages. For these packages, it is good enough for now to keep
an explicit hook to create the m4 directory.

Thanks!
