--- Comment #3 from john henning <mailboxnotfound at yahoo dot com> ---
Rainer points out that a key here seems to be that the host system compiler had
been configured with sparcv9-solaris2.11 but the 8.2.0 build did not request
the same.  In my case, the host system compiler was 7.3; Rainer reproduced with
7.4.0.

And here is a massive clue which I had missed until Rainer pointed it out:

$ file stage*gcc/dwarf2out.o
stage1-gcc/dwarf2out.o: ELF 64-bit MSB relocatable SPARCV9 Version 1
stage2-gcc/dwarf2out.o: ELF 32-bit MSB relocatable SPARC32PLUS Version 1, V8+
Required
stage3-gcc/dwarf2out.o: ELF 32-bit MSB relocatable SPARC32PLUS Version 1, V8+
Required
