    This part I agree with..

    One thing. The main benefit of $(sort), which I haven't heard you
    address yet, is to remove duplicate files. Think about 8390.o, and how
    many net drivers require it. There are two ways to handle this:

    obj-$(CONFIG_WD80x3) += wd.o 8390.o
    obj-$(CONFIG_EL2) += 3c503.o 8390.o
    obj-$(CONFIG_NE2000) += ne.o 8390.o
    obj-$(CONFIG_NE2_MCA) += ne2.o 8390.o
    obj-$(CONFIG_HPLAN) += hp.o 8390.o

    and then remove duplicates from $(obj-y) using $(sort)...

    ...Or do horrible games with 'if' statements and temporary variables
    with names like $(NEED_8390) to ensure that it gets included once if
    needed and not if not -- thereby pretty much defeating the readability
    of the new-style makefiles.

    Oh. There's a third way: ignore the issue and hope users don't feel
    the need for both ne.o and wd.o linked into the same kernel. I do hope
    you aren't advocating *that* solution, which unfortunately appears to
    be the status quo in drivers/net/Makefile. I guess solution #2 was
    seen as too much trouble there.

    The horrible games with 'if' statements have been played in any number
    of kernel makefiles and I'd really like to see them go away.

    That is the real reason I like LINK_FIRST.
