    Use lrint() from math library if available
    
    Moves -lm from being hardcoded in Makefile.am to being added via
    AC_SEARCH_LIBS in configure.ac setting it in $(LIBS)
    
    Using lrint() [returns long int] instead of rint() [returns double]
    clears a bunch of gcc warnings of the form:
    "cast from function call of type ‘double’ to non-matching type ‘short int’"
