scripts/bootstrap.sh: The Big Cleanup
This fixes the bootstrap for all architectures that we build on edge besides arm(hf|v7)
arm(hf|v7) have some issues with binutils bootstrap_armhf.txt
See also: #16368 This has been worked around in https://gitlab.alpinelinux.org/socksinspace/aports/-/tree/bootstrap-hell
I couldn't get ghc or rust bootstrapping before gcc14 (tested with aarch64 as the target), i don't have high hopes that they will suddenly work now
