On my system, "dnf repoquery --whatrequires cross-gcc-common" lists 26 gcc-*-linux-gnu packages (that is, kernel / firmware cross compilers for 26 architectures). The command "dnf repoquery --whatrequires cross-binutils-common" lists 31 binutils-*-linux-gnu packages.
The author writes, "LLVM and all cross compilers that follow it instead put all of the backends in one binary". Do those compilers support 25+ back-ends? And if they do, is it good design to install back-ends for (say) 23 such target architectures that you're never going to cross-compile for, in practice? Does that benefit the user?
My impression is that the author does not understand the modularity of gcc cross compilers / packages because he's unaware of (or doesn't care for) the scale that gcc aims at.

rustc --print target-list | wc -l

I am not an expert on all of these details in clang specifically, but with rustc, we take advantage of llvm's target specifications, so you that you can even configure a backend that the compiler doesn't yet know about by simply giving it a json file with a description. https://doc.rust-lang.org/nightly/nightly-rustc/rustc_target...
While these built-in ones aren't defined as JSON, you can ask the compiler to print one for you:
rustc +nightly -Z unstable-options --target=x86_64-unknown-linux-gnu --print target-spec-json
Anyway, it is true that gcc supports more targets than llvm, at least in theory. https://blog.yossarian.net/2021/02/28/Weird-architectures-we...
