Comment (by ballapete):

 The `configure` script has this test:

 {{{
 { $as_echo "$as_me:${as_lineno-$LINENO}: checking whether to use -latomic"
 >&5
 $as_echo_n "checking whether to use -latomic... " >&6; }
 oLDFLAGS="$LDFLAGS"
 LDFLAGS="$LDFLAGS -Wl,--as-needed -latomic"
 cat confdefs.h - <<_ACEOF >conftest.$ac_ext
 /* end confdefs.h.  */
 #include <atomic>
     int main()
     {
         static std::atomic<int> a{0};
         a = a.fetch_add(1);
         return 0;
     }

 _ACEOF
 if ac_fn_cxx_try_link "$LINENO"; then :
   qpdf_USE_ATOMIC=1
 else
   qpdf_USE_ATOMIC=0
 fi
 }}}

 Could be it is too simplistic…
