bug#23641: emacs-25.0.94 build feedback

I wrote  about a build problem of emacs-25.0.94 on FreeBSD 11

I therefore tried this:

	./configure --with-{rsvg,dbus,gconf,imagemagick}=no && make

That led to a successful build!

Compared to my earlier reported successful build using --without-all,
the newly-built emacs has 62 shared libraries, whereas the previous
one had only 30.  I have therefore installed the new build.

It might be useful to document the dependence of -lgio on those four
packages:

	rsvg dbus gconf imagemagick

because that dependence is not obvious.  Alternatively, add a
configure-time --without-gio option that suppresses those four
packages.

I don't view this as high priority, because the FreeBSD 11 package
system is clearly in error when installation of a library (-lgio) does
not install all of its dependents.

Tomorrow, I'll try a similar build on HardenedBSD 11, a new VM that I
have just finished configuring:
