krb5-config displays part of the value of CC_LINK (as set by configure,
typically from CC_LINK_SHARED as set by config/shlib.conf) with the make
variables substituted via sed:
lib_flags=`echo $CC_LINK | sed -e 's/\$(CC)//' \
-e 's/\$(PURE)//' \
-e 's#\$(PROG_RPATH_FLAGS)#'"$PROG_RPATH_FLAGS"'#' \
-e 's#\$(PROG_RPATH)#'$libdir'#' \
-e 's#\$(PROG_LIBPATH)#'$libdirarg'#' \
-e 's#\$(RPATH_FLAG)#'"$RPATH_FLAG"'#' \
-e 's#\$(LDFLAGS)#'"$LDFLAGS"'#' \
-e 's#\$(PTHREAD_CFLAGS)#'"$PTHREAD_CFLAGS"'#' \
-e 's#\$(CFLAGS)##'`
So we could omit LDFLAGS (substitute it with nothing, like we do for
CFLAGS already) while keeping the rpath options generated by the build
machinery.
