This is/was an error I likely never understand.  It seems to me that
this occurs, when (g)libtool's idea of g++ compiler is NOT the same
one which `freehdl-config --cxx` passes.  Can this be true?

Yep, that's why we get it by `freehdl-config --linker` !

As I noted before, I am not sure about the "right fix" here...  If it
works for this is fine...
