Log:
  Fix reading of .debug_line  on MIPS64, big-endian:
      read_initial_length detects pointer size by checking first
      4 bytes of .debug_line and stores it in struct comp_unit_head *
      passed to it as second argument. By passing NULL to a
      read_initial_length we ignore actual pointer size (8 bytes) and
      use default (4 bytes) which results in wrong offsets of header fields.
