I've got the zephyr sources for https://github.com/nrfconnect/sdk-zephyr.git and https://github.com/zephyrproject-rtos/zephyr (everything I get is master/main)

Okay, this freaking editor is torquing me off! I select text, set the format to "pre", go to start a new paragraph and change the format back to "paragraph" and it changes the previous "pre" as well.
It's inconsistent too as demonstrated by the changes between the texts at the top that are "paragraph/pre". It seems changing the "Font" by itself is enough. Nope. Changing the source-code it is then. Ah, finally!
Okay, after that error, I rename/move the zephyr directory and rename the sdk-zephyr directory to zephyr and run the same build command, resulting in:

Here we see it is also related to UART/CDC/ACM. Not quite sure why this is happening as doc/_build/html/boards/arm/nrf52840dongle_nrf52840/doc/index.html shows mcuboot being used in "Option 2".
EDIT0: I dropped west and went with custom attempts again and it's working for me now:
$ cmake -B./build -S./samples/zephyr/hello-world/ -GNinja -DBOARD=nrf52840dongle_nrf52840 -DCMAKE_C_FLAGS="--specs=nosys.specs" -DCMAKE_CXX_FLAGS="--specs=nosys.specs" -DZEPHYR_MODULES="<pathTo>/hal_nordic/;<pathTo>/zephyr_cmsis"
$ cmake --build ./build --target zephyr_final
EDIT1: Oh, and this was using mainline zephyr and hal_nordic from the zephyrproject-rtos repository. I tried building using mainline ARM CMSIS, but found that the zephyr CMSIS has a bunch of custom CMakeLists.txt and who knows what else, so I stuck with zephyr's version.
