[GIT PATCH] kbuild updates

[Sam Ravnborg]

Hi Linus.

Here follows kbuild updates for 2.6.17.
Most noteworthy changes:
o Introduced section consistency checks during modpost.
    This generates a number of warnings for an allmodconfig build but it
    looks sane for most normal configs.
    There may be false positives around but they are getting less.
o Removed scripts/reference_* - they are replaced by the check for
  inconsistent section usage
o Introduced check for duplicated exported symbols
o Make kbuild compatible with a future gnu make change
o Improved support for external modules (depmod, exported symbols)
o Lindent a few files (modpost.c, genksyms.c) addidng to size of diff.

Almost all patches have been in -mm for a shorter or longer period.
Shortlog contains more details.
Patches (all 48) will follow as separate mails.
