[ISOLATED] Re: was error in latest build, svn 15200: Enable getopt long

[Robert P. J. Day]

  ok, here's the deal.  it's that nasty

#include <asm/byteorder.h>

in hdparm.c that's causing the problem.  if i just flat out delete
that line, then

  $ make defconfig busybox

builds just fine until the very end:

  AR cru libbb/libbb.a
  LINK busybox_unstripped
/home/rpjday/bbx/busybox.new/miscutils/miscutils.a(hdparm.o): In function `process_dev':
hdparm.c:(.text+0x2b24): undefined reference to `__le16_to_cpus'
/home/rpjday/bbx/busybox.new/miscutils/miscutils.a(hdparm.o): In function `hdparm_main':
hdparm.c:(.text+0x2d11): undefined reference to `__le16_to_cpus'
collect2: ld returned 1 exit status
make[1]: *** [busybox_unstripped] Error 1
make: *** [busybox] Error 2

  so, sure, losing that include means that "__le16_to_cpus" is
undefined, but we shouldn't be using that routine by including it from
that header file anyway.  that header file is, as it warns at build
time, a *private kernel header*.

  so what's the *proper* way to do this?  and whatever it is, it
shouldn't involve including private kernel header files.
