When using Solaris ld instead, all tests can be linked (modulo removal of
-z norelo since Solaris doesn't support relro).
I wonder how best to handle this: bfd/elfxx-sparc.c
(_bfd_sparc_elf_relocate_section) already silently ignores the overflow in a
few select cases (like .stab sections), following the lead of Solaris ld. As
expected, the tests do PASS if I do this unconditionally for the 3 affected
relocs.
This may or may not be a hack, though.
