Perhaps weirder, it seems to be triggered by an inclusion of armadillo_bits/constants.hpp in both my shared object and the Rcpp binding library-which seems like something that shouldn't be raising any issues.

Seemingly, yes. ODR stands for _One_ Definition Rule so if you define 
the same thing in two different libs then raising issue sounds legitimate.
I suppose one possible solution could be incorporating the content of 
libnmflib.so (and all other libs your build) directly in RcppPlanc.so 
and cleaning them afterward.

Hoping it helps,
Serguei.
