Fix bad gp value in elfNN_ia64_choose_gp

Fix bad gp value in elfNN_ia64_choose_gp

[Andreas Schwab]

elfNN_ia64_choose_gp chooses a bad gp value because os->size is not set
until final link.  If .sbss is very large the gp value chosen during final
link will vary wildly from the chosen value during the relaxation pass and
some of the relaxed GPREL22 relocations may overflow.

Thanks.  This is good.

I see that it was changed from _raw_size to size via a large rewrite,
and this large rewrite failed to recognize that this is a relax related
function, and hence should have used rawsize in the first place.
