--- Comment #3 from Ali Bahrami <ali_swbugzilla at emvision dot com> ---
As additional evidence that binutils/bfd are wrong
in preventing more than one SHT_SYMTAB_SHNDX, I'd like
to reference this discussion in the ELF gABI list where
we just modified the ELF spec to make it clear that
multiple such sections are allowed:

    https://groups.google.com/forum/#!topic/generic-abi/-XJAV5d8PRg

So binutils should be fixed. However, I think it's
also probably true that the Illumos ld, as with the
Solaris ld, needs to be updated to understand the
special section merging rules that the GNU linkers use
to remerge the sections that result from the use of
-ffunction-sections. Extended sections really shouldn't
occur in an executable or shared library.
