Note the FAILs are in the stdio log, but not (???) in the rust.sum or
rust.log files. I don't understand why yet:

FAIL: rust/execute/torture/builtin_macros1.rs   -O0  output pattern test
FAIL: rust/execute/torture/builtin_macros1.rs   -O1  output pattern test
FAIL: rust/execute/torture/builtin_macros1.rs   -O2  output pattern test
FAIL: rust/execute/torture/builtin_macros1.rs   -O3 -g  output pattern test
FAIL: rust/execute/torture/builtin_macros1.rs   -Os  output pattern test
FAIL: rust/execute/torture/builtin_macros1.rs   -O2 -flto -fno-use-linker-plugin -flto-partition=none  output pattern test
FAIL: rust/execute/torture/builtin_macros1.rs   -O2 -flto -fuse-linker-plugin -fno-fat-lto-objects  output pattern test

They only seem to fail on s390x.
