[PATCH 0/18] kbuild fixes

[Sam Ravnborg]

Hi Linus.

Here is a number of small and smaller kbuild fixes for -rc2. Please add
them before -rc3.
The list got larger than expected since I missed -rc1 with half a day.

Most noteworthy:

o fix build on ubuntu - breakage caused by -fno-stack-protector enabled
  on ubuntu
o fix building out-of-tree modules
o fix 'make headers_install' to work with a non-configured kernel
o added unifdef to the kernel tree. It is not a widely distributed tool
  author has acked this

Patches has been in -mm for a while with no bugs reported.
Exception is the 'linguistic fixes' - but they did not cause any
compile/boot issues ;-)

Please pull from:

diffstat + shortlog + full log below.

	Sam

    remove RPM_BUILD_ROOT from asm-offsets.h
    
    No file in rpm binary package should have the RPM_BUILD_ROOT string in it.
    To simplify building of external modules, our kernel-source package
    contains some temp files from the Kbuild system.  asm/asm-offsets.h is one
    of the files that contains the absolute path if make O=$O is used.
    
      * This file was generated by /var/tmp/kernel-source-2.6.14_rc4-build/usr/src/linux-2.6.14-rc4-2/Kbuild
    
    Remove the $RPM_BUILD_ROOT string in the shipped tempfile.

    kbuild: add unifdef
    
    This patch contains a raw copy of unifdef.c
    Next patch will modify it and add infrastructure to use it
    Adding unifdef to the kernel is acked by the author.
    
    The reason to add unifdef as part of the kernel source is that it is not
    yet a common utility on most distributions.

    kbuild: consistently decide when to rebuild a target
    
    Consistently decide when to rebuild a target across all of
    if_changed, if_changed_dep, if_changed_rule.
    PHONY targets are now treated alike (ignored) for all targets
    
    While add it make Kbuild.include almost readable by factoring out a few
    bits to some common variables and reuse this in Makefile.build.

    kconfig: support DOS line endings
    
    Kconfig doesn't currently handle config files with DOS line endings.
    While these are, of course, an abomination, etc, etc, it can be handy
    to not have to convert them first.  It's also a tiny patch and even adds
    support for lines ending in just \r or even \n\r.

    kconfig: correct oldconfig for unset choice options
    
    oldconfig currently ignores unset choice options and doesn't ask for them.
    Correct the SYMBOL_DEF_USER flag of the choice symbol to be only set if
    it's set for all values.

    The original errormessage was just plain unreadable.
    
    Sample error message after this update (not for real - I provoked it):
    
    FATAL: drivers/net/s2io: sizeof(struct pci_device_id)=33 is not a modulo of the
    size of section __mod_pci_device_table=160.
    Fix definition of struct pci_device_id in mod_devicetable.h
    
    Before a warning was generated - this is now a fatal error.
