libudfread needs __sync_*_4 or threads since its addition in commit
c477885e3f3c31d3922af1fc0e47e6f5f35b1645 and
https://code.videolan.org/videolan/libudfread/-/commit/06c3cb9223a3cb5ab048e42ab353958f422a8f57
to avoid the following build failure:

src/udfread.c:108:3: error: #error no atomic operation support
  108 | # error no atomic operation support
      |   ^~~~~
