Log:
  ar: detect and error out on 32-bit symbol table overflow

  BSD ar currently does not support the /SYM64/ 64-bit symbol table, and
  previously truncated to 32-bits, silently producing corrupted archives
  larger than 4GB.

  Note that this is only a partial fix; additional checks will come.
