Bug#972317: FTBFS on ppc64el

[Stéphane Glondu]

Package: src:llvm-toolchain-9
Version: 1:9.0.1-14
Severity: serious
Tags: ftbfs

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
>     clang-9: note: diagnostic msg: PLEASE submit a bug report to https://bugs.llvm.org/ and include the crash backtrace, preprocessed source, and associated run script.
