Probably this happens since gcc-4.3 due to this commit:
https://gcc.gnu.org/viewcvs/gcc/trunk/gcc/varasm.c?r1=119764&r2=119763&pathrev=119764

Problem is that assemble_external() does not call ASM_OUTPUT_EXTERNAL any more
to add the decorations, before the symbol is written via ASM_OUTPUT_SYMBOL_REF.
