As I mentioned in an earlier email, this is necessary on the v850
because the default -r linker-script merges .gnu.linkonce.t* into the
.text output section. I don't think it will hurt any other platforms.

No! Does this not work?

That'll probably work too.
[Though since the module loader depends on .gnu.linkonce.this_module
being a unique section, I think the global option should be OK as well]
