rustc_codegen_ssa: Define ELF flag value for sparc-unknown-linux-gnu Currently, attempting to build this target using Ubuntu/Debian's sparc64-multilib toolchain results in the following link error ([full log](https://github.com/taiki-e/atomic-maybe-uninit/actions/runs/22798868888/job/66137493862#step:15:442)): ``` = note: /usr/lib/gcc-cross/sparc64-linux-gnu/13/../../../../sparc64-linux-gnu/bin/ld: unknown architecture of input file `/home/runner/work/atomic-maybe-uninit/atomic-maybe-uninit/target/sparc-unknown-linux-gnu/debug/deps/rustcYzaDYW/symbols.o' is incompatible with sparc:v8plus output ``` This appears to be caused by the required e_flag being missing and can be fixed by setting `EF_SPARC_32PLUS`. Tested using rustc with this patch applied and qemu-user (https://github.com/taiki-e/atomic-maybe-uninit/commit/57d7e7f9905cb5f7bc1254e5527af27b42c99c6a, [log](https://github.com/taiki-e/atomic-maybe-uninit/actions/runs/22798793270/job/66137298093)).
