This is usually handled in gcc/config/sol2.c
(solaris_elf_asm_comdat_section, solaris_define_comdat_signature,
solaris_code_end). I haven't yet checked why this doesn't trigger here.

Me too: this should be local to the Solaris port if at all possible. I
won't argue if the need to explicitly define the signature symbols is a
bug or just different from gas, though :-)
