[PATCH] D105453: [mlir][SystemZ] Disable `-fno-semantic-interposition` option.

[Fangrui Song via Phabricator via llvm-commits]

MaskRay added a comment.

It'd be good to know which gcc bug this is.

Perhaps just exclude SystemZ for all configurations, instead of checking `"mlir" IN_LIST LLVM_ENABLE_PROJECTS`.

We generally still want -fno-semantic-interposition because gcc -fno-semantic-interposition built clang can be 3% faster on benchmarks.
