Fixed bug in Item_func_compress::val_str() on MacOS X (bigendian); the length

was not properly stored in the buffer.


sql/item_strfunc.cc:
  Made it work on MacOS X (bigendian) where int4store is a macro that expands
  the arguments several times.
  It's possible this should be done differently, like not side-stepping the
  String methods the way it's done here, or fixing String::c_ptr(), but this
  simple fix was the quickest way.
