any reason you want to build specifically 8.4.3? And any specific
reason you want to use 8.0.2 to build it? Anyway, you likely don't
want to build unregistered, but use the llvm backend.
You want to set the BuildFlavour to quick-cross, e.g. with
sed -E "s/^#BuildFlavour[ ]+= quick-cross$/BuildFlavour = quick-cross/" < mk/build.mk.sample > mk/build.mk
Once you have your compiler built, you'll likely want to use toolchain
wrapper to make things a bit easier.
If you just want to try to build some simple code for a raspberry pi, you
could also try the experimental pre-built cross compilers from
