The problem I encountered relates to using "qemu-*-static" to perform builds in a chroot. It doesn't affect using "qemu-*-system" to perform builds on a whole emulated system. And yes, it only affects running the testsuite, not building packages. Basically, "qemu-*-static" thinks in single processes, and emulated "atomic operations" are only properly emulated for threaded programs, not multiprocess programs which map the same data in multiple processes and then access them using an atomic memory model.
