/* For a SYMBOL_REF, set generic flags and then perform some

Set SYMBOL_FLAG_SMALL_V4 for an operand in small memory on V.4/eabi;
this is different from the generic SYMBOL_FLAG_SMALL.
When the AIX ABI is requested on a non-AIX system, replace the
function name with the real name (with a leading .) rather than the
function descriptor name. This saves a lot of overriding code to
