Well, that's really confusing, I was expecting something like 'missing
arguments' like the ld.gold does.  :-)

I'am asking this because when I'm doing this:  (all are non binary object)
ld.gold -plugin=/path/to/plugin  a.o b.o c.o
everything goes fine.

but
ld -plugin=/path/to/plugin  a.o b.o c.o
complains  b.o: file not recognized: File format not recognized

If the plugin interface is the same, there should not be any problem, right?

btw, I'm using the LLVM gold plugin, which implements the gold interface.
