In ld.so.1 if it gets "randomly" prelinked at inappropriate address to clash
with the (fixed) application address space.
On 32-bit (ppc) unfortunately `prelink -R' in fact is not random so on some
systems this unfortunate clash may occur permanently breaking GDB a bit.

FYI elfutils has _SDA{,2}_BASE_ exception in its elflint so assuming for GDB
more some `set complaints' style complaint.
