    gnu: openfst-1.7.3: Enable ngram-fst extension & C++14 build
    
    The extension doesn't build in old versions of openfst such as 1.7.3 without
    manually setting CXXFLAGS.
    
    This package definition, including this workaround to build extensions
    successfully, will need to be removed once kaldi is fixed upstream and can 
be
    used with up-to-date versions of openfst.
    
    * gnu/packages/machine-learning.scm (openfst-1.7.3)[arguments]: New field.
