This revision is now accepted and ready to land.

In glibc, DLFO_STRUCT_HAS_EH_DBASE is only defined on i386 and nios2. We don't support nios2.

glibc/elf/dl-find_object.h says that when DLFO_STRUCT_HAS_EH_DBASE is 1, eh_dbase is the relocated DT_PLTGOT value.
I assume that means our DW_EH_PE_datarel is possibly wrong.
