Update src/Makefile to enforce OpenFst >= 1.5.3.

dogancan · dogancan · commit b23f7205c9b5 · 2017-01-18T13:50:25.000-08:00
OpenFst-1.5.3 adds support for minimization of non-deterministic FSTs
over idempotent semirings which is a feature used throughout Kaldi.
Along with the requirement for a C++ compiler with C++11 support, we
are also removing support for older OpenFst releases so that we can
build against an un-patched OpenFst installation.
