+Subject: [PATCH 12/15] Ignore broken and non-applicable tests
+
+c-link-to-rust-va-list-fn: unstable feature, broken on aarch64, #56475
+env-funky-keys: can't handle LD_PRELOAD (e.g. sandbox)
+long-linker-command-lines: takes >10 minutes to run (but still passes)
+simd-intrinsic-generic-bitmask.rs: broken on BE, #59356
+sparc-struct-abi: no sparc target
+sysroot-crates-are-unstable: can't run rustc without RPATH
