dmd -> ldmd2: /usr/bin/ld.gold: error: .o: multiple definition of 'bool ldc.attributes...

[kdevel via Digitalmars-d-learn]

After replacing dmd with ldmd2 (LDC 1.25.1) I get tons of link 
errors all of
the form mentioned in the subject. Any idea what can be done 
about it?

(With a handcrafted single compile/link statement using ldc2 
everything compiles
but ideally I want to reuse my Makefile).
