No need: plugins just work on both platforms, both with the vendor tools
and gld (on Solaris, gld is currently broken for IRIX).

Doesn't matter: even if you bootstrap with the vendor compiler (works on
Solaris, still on my agenda for IRIX), stages 2 and 3 are built with
gcc. With the native linkers, -rdynamic isn't needed and
gcc/configure.ac handles this just fine. In my case, I had to introduce
-rdynamic support into gcc so plugins work with gld:

That's certainly an important goal: currently, we have several hidden
dependencies like that that influence what features the GCC just build
has. This should be made more transparent.

As I said, the bootstrap compiler isn't relevant here. But *please*
avoid introducing new failure modes for other platforms in your effort
to improve Darwin support.
Thanks.
