 manual definition of struct user_pt_regs
 On ARM64, libunwind uses struct user_pt_regs which is not defined in
 anywhere, which causes FTBFS.

 replace the legacy __sync built-in functions with __atomic ones
 libunwind uses the built-in __sync_* functions which are deprecated by GCC and
 should be replaced by __atomic_* ones. See the official manuals [1].
 .
 The legacy __sync functions do not require to specify the memory order but
 __atomic ones do, so we choose the strongest one: __ATOMIC_SEQ_CST.
 .
 We do this because __sync_fetch_and_add() is not supported on armel.
