Optimizing Makefiles

[Akim Demaille]

What is the general policy wrt `optimizations' in automake vs leaving
some job to make?  For instance there are many places with code like:


                if ($relative_dir eq '.')
                {
                    push (@files, 'acconfig.h');
                }
                else
                {
                    push (@files, '$(top_srcdir)/acconfig.h');
                }

While it certainly more elegant from the Makefile point of view, it
results in many little places in automake where the core code is
``polluted''.  Don't we want to continue like this?
