This is due to a gcc bug:
  https://gcc.gnu.org/bugzilla/show_bug.cgi?id=81358

The usual workaround would be something like:
  ifneq (,$(filter $(DEB_HOST_ARCH), armel m68k powerpc sh4))
    export DEB_LDFLAGS_MAINT_APPEND += -Wl,--no-as-needed -latomic -Wl,--as-needed
  endif

But this workaround would work poorly when the atomic usage is
in a static library.

Could findlib emit -latomic at the end of the libraries
on these architectures?
