[Pkg-openssl-devel] Bug#1015792: openssl: Explicitly use libatomic on ARC/NIOS2/SPARC

[Alexey Brodkin]

Package: openssl
Version: 1.1.1f-1ubuntu2.12
Severity: normal
Tags: patch

Dear Maintainer,

openssl fails to build on 32-bit architectures such as ARC, NIOS2 & SPARC
due to the fact that 64-bit atomisc are not natively supported.

Though with use of libatomic that problem gets solved, see
upsream openssl discussion here https://github.com/openssl/openssl/pull/15640.

And solution is as simple as the patch below:

That's because "linux-latomic" bascally extends "linux-generic32"
with addition of "-latomic" flag for the linker.

And for the record, "linux-latomic" is already used for the rest
of 32-bit architectures. So nothing new here.
