# Description:
#   gnu make makefile rules for elftosb executable.  make needs to be called
#   with the following command:
#
#   make -C ${BUILD_DIR} -f ${SRC_DIR}/makefile.rules SRC_DIR=${SRC_DIR} $@;
#
#   SRC_DIR needs to be passed in.  It is assumed that make is running in
#   the build directory.
