Allow external configuration of endianness in R package build (#10642)
* Allow users to set endianness in R build * Run `autoreconf -vi` * Don't use :BOOL suffix * Use AC_CONFIG_HEADERS --------- Co-authored-by: Hyunsu Cho <phcho@nvidia.com> Co-authored-by: Philip Hyunsu Cho <chohyu01@cs.washington.edu>
