I saw this today on x86_64/zero, and it seem Zero-specific:
  https://builds.shipilev.net/openjdk-jdk/openjdk-jdk-b215-x86_64-zero-fastdebug.build.log

...but, curiously, it was not reproducible with my local builds. I decided to wait another nightly
before diving in. FWIW, I am not sure why share/opto is even built when compiler2 is disabled.
