I'm having a bit of trouble understanding how to actually get

I've installed the latest LDC and LLVM releases for Windows,
though the -mcpu does not have any AVR options out-of-the-box
as you mentioned. Perhaps I've missed something, or will I need
to build the binary myself using the flags for AVR?
Compiling the sample from the AVR wiki works here on Win64 with
the official LDC 1.22 package and:
ldc2 -betterC -Oz -mtriple=avr -mcpu=atmega328p -c test.d
For linking, you'll need an avr-gcc toolchain, and add
`-gcc=<path\to\avr-gcc> -Xcc=-mmcu=atmega328p` as mentioned on
the Wiki page. I don't have such a toolchain.
The ESP32 process seems more involved. Due to my inexperience
in this area, I'm wondering that, if I need to build the
binaries myself anyway, how I would set it such that it'll work
with AVR and ESP32 at the same time with one installation?
Simply using -mtriple and tweaking etc\ldc2.conf as explained
