RTEMS 4.12 on RPi Zero

I've been having a lot of trouble attempting to get RTEMS running on a 
Raspberry Pi Zero, hoping someone can help.

I've been following the steps outlined by 
but changing all references of 4.11 to 4.12 and omiting /chrisj/ from 
the git path for rtems builder. My primary environment is Bash for 
Windows running Windows 10 Pro, however I have an Ubuntu 17.04 install 
that can target the exact same directory.

At first, I made a brand new Raspbian boot SD and then replaced the 
kernel.img on the SD card with the img file created in Alan's last step, 
however that never does anything. One of the comments from that post had 
said to use the ticker.exe from 
instead of under /bsps however that too does not work. At this point I 
also noticed that the Makefile in /build-rtems-rpi/...../ticker hadn't 
fully run. When I ran that makefile, it failed saying that leaf.cfg:1 
*** missing separator. Stop.

I have copied the 4.11.2 tarball from 
https://git.rtems.org/rtems-source-builder/ and build up the source 
builder from that, however when I get to the make install step, it 
errors out as several make files that it tries to run during the 
recursive step don't have install steps (or any steps, they're blank) so 
the make process stops.

Any pointers or tips on how to get this working would be greatly
