Marcel Moolenaar 30ec71ad04 Unbreak ia64. 
With r169630 I disabled symbol versioning because it broke rtld.  With
r211706 rtld got broken for ia64 & powerpc64.  It was fixed for powerpc64
with r212497.  In between, r211749 removed the exports table because the
version script handled the exports.  But wait, symbol versioning was
disabled on ia64.

With exports controlled by the version script and symbol versioning
disabled, all symbols are exported and too many symbols bind to the
definition in rtld. Let's just say that waird things happen.

So, enable symbol versioning on ia64 and apply a work-around for the
SIGSEGV that triggered r169630 to begin with: when rtld relocates
itself, it comes across r_debug_state and for some reason can't find the
definition. This causes a failure, relocation aborts and null pointers
galore. The work-around is to ignore the missing definition when rtld
is relocating itself and keep going.

Maybe with the next binutils this will all go away. Maybe not, in
which case I still need to figure out why r_debug_state cannot be found.

BTW: r_debug_state is in the symbol map -- I don't think any other rtld
symbols that rtld references are in the symbol map...
