Those errors in both logs seem fairly odd. The first one appears to be mostly a missing libgmp, the second one looks like hsc2hs's template file is missing, however hadrian should have a rule for that.
You can try to clean your tree and rebuild. git clean -xfd git submodule foreach git clean -xfd git submodule update --init --recursive ./boot && ./configure cabal v2-update hadrian/build -j --flavour=Quick/boot In general the instructions on https://ghc.dev are pretty good.
