Rollup merge of #114496 - taiki-e:sparc32-atomic, r=Amanieu 
Set max_atomic_width for sparc-unknown-linux-gnu to 32

This is currently set to 64

90f0b24ad3/compiler/rustc_target/src/spec/sparc_unknown_linux_gnu.rs (L8)

However, AFAIK, this architecture doesn't support 64-bit atomics, and LLVM generates libcalls: https://godbolt.org/z/chzThWGG1

(Currently, attempts to run `cargo test` for this target result in "undefined reference to `__sync_val_compare_and_swap_8'" error. 02efe1e74f)
