If I can figure out when full support for .gnu.linkonce started in
Solaris ld, I can make this dynamic in configure.ac ...

... like this one: complete Solaris ld support for comdat started
sometime in the Solaris 11 timeframe, cf. configure.ac (comdat_group).
Solaris 10 did not (at least not in a way that could cope with
everything gcc might generate).
