A typo in elfNN_ia64_choose_gp?

[H. J. Lu]

Hi Richard,

elfNN_ia64_choose_gp tries to pick a good gp. But it also counts
the text sections when it computes min_vma and max_vma. Since there
is a huge gap between the text segment and the data segments on
Linux, the linker always picks the address of GOT as gp. On Linux,
GOT is the lowest address of small data:

As the result, we can't support as much short data as we should. Do
we have to count text sections for min_vma and max_vma? I'd like to
change them to min_data_vma and max_data_vma, and use them to pick
a better gp.

Thanks.
