No, that's weird, unless there's something about the ia66 ELF format
that requires one set of relocs be applied before others can be done
correctly.  I don't know enough about ia64 to know whether this is
the case, but it's true on other targets.  eg. powerpc64 ld.so needs
to relocate the .opd section before applying .plt relocs as the .plt
relocs copy .opd section data.

See the place_orphan function in ld/emultempl/elf32.em.
