With a minor build fix the selftest passes for me on ppc64le:

  # ./close_range_test 
  1..9
  ok 1 do not allow invalid flag values for close_range()
  ok 2 close_range() from 3 to 53
  ok 3 fcntl() verify closed range from 3 to 53
  ok 4 close_range() from 54 to 95
  ok 5 fcntl() verify closed range from 54 to 95
  ok 6 close_range() from 96 to 102
  ok 7 fcntl() verify closed range from 96 to 102
  ok 8 close_range() closed single file descriptor
  ok 9 fcntl() verify closed single file descriptor
  # Pass 9 Fail 0 Xfail 0 Xpass 0 Skip 0 Error 0
