Hi Manuel & Erik
I think I know why MIPS is broken. _dl_perform_mips_global_got_relocations() is
broken. It will due to my latest changes reloctate ldso. This
function needs to die and its job should be done inside _dl_parse_relocation_information().
It is mostly a copy and paste job,
Also PERFORM_BOOTSTRAP_GOT and PERFORM_BOOTSTRAP_RELOCATION should be fixed, they
use symbols which aren't passed as arguments.
