That is not how most ELF linkers behave, although Daniel suggested
that the Irix linker does behave that way.  Most ELF linkers create
both a normal symbol and a dynamic symbol table when linking against a
shared object.  I expect that there is some way to tell the Irix
linker to do the same.  In general, the dynamic symbol table need only
contain symbols which are dynamically linked; the normal symbol table
is normally larger.

I'm sorry, I don't know why it isn't working.
