Something is missing in the pcrel2.d file, it seems.  Other than
that, it seems ok.

A thought here.  Isn't this commonly generated by gcc in the
absence of -fpic/-fPIC?  If so, then I guess -fpic/-fPIC is
required for DSO:s and there's no support for DT_TEXTREL.
Is that the case?  (I don't mind, though; -fpic/-fPIC is
required for CRIS but elf32-cris.c emits an error message in
elf_backend_check_relocs when bad relocs are found when
-shared.)
