${OBDIR}/releasedir/evbarm/binary/gzimg should contain a file
armv7.img.gz, I believe you should be able to gunzip | dd that onto an
SD card and have a working installation, /boot file system and
everything.  It is my understanding that upon first boot this will
grow the file system to the full size of the SD card.

That should give you two files, rpi.img.gz and rpi_inst.img.gz in
${OBJDIR}/releasedir/evbarm/binary/gzimg, rpi_inst.img.gz is a gzip'd
sshramfs installer image (boots into sysinst from where you then can
do an installation from network onto the SD card) and rpi.img.gz is a
gzip'd installation that you can use directly.

So just to make sure, do you mean rpi.img(.gz) or do you *actually*
have a file rpi2.img(.gz)?

I think armv7.img is to the Raspberry Pi 2/3 what rpi.img is to the
Raspberry Pi 0/1.  At least mostly - the FAT boot partition on
armv7.img *additionally* contains the files required to boot on other
evbarm boards like the BeagleBoard.  So armv7.img probably is the
image you are looking for.

(Note that I haven't used either of these images myself, my
installations were done with the sshramfs image.  I suppose it's
mainly a matter of personal preference - for me it's probably mostly
that I tend to avoid growing existing file systems and prefer creating
them in the final size from start, at least if possible.)
