I think the final conclusion on this problem in the old thread was that the 
assembler is generating ELF files that are IRIX flavored with respect to the 
symbol table ordering and index. I discovered by playing around that the linker 
was creating
correct ELF symbol tables, so as a temporary work around until the assembler is 
tweaked I started to incrementally link my modules with the linker `ld -r 
<filename>` . This eliminated the immediate problem for me.
