Bug#978113: clang++ fail to compile programs

[Sylvestre Ledru]

control: severity -1 normal

Hello,

Lowering the severity as clang++ is used on s390x for a bunch of programs.

Including clang which is built using itself:

https://buildd.debian.org/status/package.php?p=llvm-toolchain-11

Dear Maintainer,

Clang++ can not operate on s380x and does not compile any C++ program.

Could you please try to generate it into a regular file?
