That option must be used with -fno-implicit-inline-templates in my case
but, as pointed out elsewhere, this was really a gcc problem, not a
linker problem.

and playing a bit with this once I solved the problem above shows that
the toolchain's default behavior is to actually import all
non-instantiated templates. So, the question was moot.

sorry about the noise,
