From f5a08880d80d31a9c93c990206602b05b797e500 Mon Sep 17 00:00:00 2001 From: Benjamin Barenblat Date: Tue, 9 Feb 2021 19:41:06 +0000 Subject: [PATCH] Use libatomic if necessary Bug-Debian: https://bugs.debian.org/973492 On some architectures, notably armel, Abseil needs symbols defined in libatomic. Abseil does not currently have a well-developed system to declare external library dependencies, so just have the linker determine if anything needs libatomic and add the DT_NEEDED entry where necessary.
