Thanks for quick response.
I don't know how to run the testsuit. I have MIPS platforms. I'd like
to know if you can kindly point me to an instruction on how to run
the testsuit. So I can setup test quickly.
And I wonder if setting the __GLOBAL_OFFSET_TABLE___ as Local is
another soluation. As the following:
if (! (_bfd_generic_link_add_one_
(info, abfd, "_GLOBAL_OFFSET_TABLE_", BSF_LOCAL, s,
0, NULL, FALSE, get_elf_backend_data (abfd)->collect, &bh)))
