Oh.  _dl_make_fptr is … complex.

For a static function such as openaux, I would have expected the static
linker to allocate space for a function descriptor and initialize it
using an R_IA64_REL64LSB relocation.  Isn't this how other targets with
function pointers handle it?  However I see now that hppa has a similar
relocation (R_PARISC_PLABEL32), but at least that is non-symbolic.

Thanks,
