build: use ifdef and not m4_ifdef for silent rules

I do not understand why silent rules should be default, even per
automake manual:

"""
Note that silent rules are disabled by default; the user must enable
them explicitly at either configure run time or at make run time. We
think that this is a good policy, since it provides the casual user with
enough information to prepare a good bug report in case anything breaks.
"""

However, if we want this, best use the autoconf verbs.
