Severity: serious

Dear Maintainer,
Your package FTBFS on ppc64el:
https://buildd.debian.org/status/package.php?p=llvm-toolchain-9
The rebuild was triggered by the update of OCaml from 4.08.1 to
4.11.1, but the error looks independent (I might be wrong).
The build log ends with:
clang-9: error: unable to execute command: Segmentation fault
clang-9: error: clang frontend command failed due to signal (use -v to see
invocation)
clang version 9.0.1-14+b1
Target: powerpc64le-unknown-linux-gnu
Thread model: posix
InstalledDir: /<<PKGBUILDDIR>>/build-llvm/tools/clang/stage2-bins/bin
