You're right, the package manager isn't putting stuff in /usr/local. I
am, as well I should. That's what it's there for.
Why is the emacs configure script traversing /usr/local in search of
include files? That's the more pertinent question to this list. The
behavior is wrong, even on its own terms. I just happened to have a
setup that exposes it.

Gee, I thought it was pretty plain what I'm up to: installing emacs
from source. The configure script broke on my system and suggested
--no-png as an option. Since I knew I had libpng installed, and
couldn't upgrade it (under Ubuntu LTS as of December 2016),
I asked some questions here. That led to the discovery that configure
was using an include directory it had no right to.
configure has every reason to look in /usr/include
and /usr/local/include. There's no justification for rooting around
the entire /usr/local. Especially if it doesn't also do the same for
the associated library. The configure test is, simply, broken.
In the event, my workaround worked: I renamed the anaconda directory
to /usr/local/.anaconda. configure ignored it, and emacs built just
fine. As an added bonus, having read INSTALL carefully, I excluded the
dbus stuff and no longer see warnings when emacs starts up. I think I
just heard an angel get its wings.
Below, for the record, is the final Makefile I used. It prepares
Ubuntu to build packages, fetches and builds emacs, constructs a binary
Debian package (IIUC), and installs it. I hope it is useful to someone
My original question was how to use the fonts I want. Kudos to Javier
for pointing me in the GTK direction, correctly suggesting that fixing
that would fix the font issue, too.
