I think the linker tests are very limited. Much more testcases are
# grep STT_OBJECT elf*.?
shows that you need to handle STT_COMMON in many places. I believe
assembler should generate STT_COMMON only when
type foo, %common
is used. Also linker should generate STT_COMMON in shared library
and executable only when STT_COMMON in object file is seen.
_bfd_elf_merge_symbol and others should to modified to handle it.
Also I don't think it should be a configure time option at command
