Bug#1079077: mozjs128: Fails to build on armel

[Jeremy Bícha]

Source: mozjs128
Version: 128.1.0-1
Severity: important
Tags: ftbfs
User: debian-arm at lists.debian.org

mozjs128 fails to build on armel, apparently because of atomic
operations. Assistance is requested because we want to switch gjs from
mozjs115 to mozjs128 soon.

I attempted a very simple -latomic fix but it failed. mozjs has a more
complicated buildsystem so maybe I didn't set it in the right place.
