Although common symbols are defined in executables, they aren't in small
data section. But a definition in small data section overrides a common
symbol, which still binds lcoally, and turns a reference to common symbol
to reference to small data section. Even if ia64_in_small_data_p returns
true on common symbols, sdata_symbolic_operand must return false on common
symbols. Common symbols are assumed to be placed in small data section,
but are accessed as if they are in normal data section so that they won't
cause any relocation overflow.
