      Systems that want to
    arrange for sysconfdir to be /etc when --prefix=/usr just have to
    install /usr/(share|etc)/config.site with:

    test "x$sysconfdir" != 'x${prefix}/etc' || sysconfdir=/etc

I think you have misunderstood what I proposed, because this would not
implement it.  We are failing to communicate.  I will try explaining
the proposal at greater length; then maybe it will be clear.

My proposal is that if you do just `make install' then the default for
prefix and sysconfdir (and maybe some other variables) should be the
same as now.  But `make install standard_system=yes' would use
different system-specific defaults for prefix and sysconfdir (and
maybe some other variables).

Perhaps on most systems those system-specific defaults would be
prefix=/usr and sysconfdir=/etc.

I think your proposed implementation would set the default for
sysconfdir at configure time, and would not be conditional at make
time.  So we are not talking about the same thing.
