In Rcpp versions prior to release 0.10.1 of November 2013,
LdFlags and RcppLdFlags were used to return the required
flags and options for the system linker to link to the Rcpp user
library. Since we no longer build or ship a user library, these
functions now return an empty string. As of Rcpp release 0.12.19,
these functions are now deprecated.
