Bug#972318: FTBFS on ppc64el

[Stéphane Glondu]

Package: src:llvm-toolchain-10
Version: 1:10.0.1-6
Severity: serious
Tags: ftbfs

Dear Maintainer,

Your package FTBFS on ppc64el:

  https://buildd.debian.org/status/package.php?p=llvm-toolchain-10

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:
> ar ruv libFuzzer.a Fuzzer*.o
> -g -O2 -fdebug-prefix-map=/<<PKGBUILDDIR>>/build-llvm=. -fstack-protector-strong -Wformat -Werror=format-security -Wdate-time -D_FORTIFY_SOURCE=2
> Segmentation fault
> ar: `u' modifier ignored since `D' is the default (see `U')
> ar: creating libFuzzer.a
> ar: Fuzzer*.o: No such file or directory
> make[1]: *** [debian/rules:420: debian-libfuzzer-build] Error 1
> make[1]: Leaving directory '/<<PKGBUILDDIR>>'
> make: *** [debian/rules:286: binary-arch] Error 2
> dpkg-buildpackage: error: debian/rules binary-arch subprocess returned exit status 2


Cheers,
