34 * Kbuild is not very cooperative with respect to linking separately
35 * compiled library objects into one module. So for now we won't use
36 * separate compilation ... ensuring init/exit sections work to shrink
37 * the runtime footprint, and giving us at least some parts of what
38 * a "gcc --combine ... part1.c part2.c part3.c ... " build would.
