And we've been discussing with Yar how this can be improved
before this bikeshed ever started.

One idea was to add a sys.mk(7) manpage documenting what it
does, but I thought it was an overkill given a relatively
small amount of information that could be put there.
Documenting (briefly) what the standard FreeBSD sys.mk file
does in a separate section in the make(1) manpage shouldn't
be a problem, but in this case I insist it should be made
clear this is specific to FreeBSD and not the make(1) itself.
Having /etc/make.conf included with every make(1) run is a
design bug. It's a bug because the implementation doesn't
match the goal. The goal (as advertised in the make.conf
manpage) is to "contain settings that control the compilation
of the FreeBSD sources and ported applications" and "it is
included by the various makefiles in /usr/src, /usr/ports
and /usr/doc". I mean, the visibility of /etc/make.conf
would better be constrained by src/, ports/, and doc/
makefiles, not the universe under the control of FreeBSD.
I think it's too late to change that, so we'll have to
live with this backward compatibility bug or come up
with a better replacement. NetBSD, for example, that
has a very elegant build system, doesn't suffer from this
bug. They only include their mk.conf for system builds.
