Merge branch 'kbuild' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild

Pull kbuild changes from Michal Marek:

 - Alias generation in modpost is cross-compile safe.

 - kernel/timeconst.h is now generated using a bc script instead of
   perl.

 - scripts/link-vmlinux.sh now works with an alternative
   $KCONFIG_CONFIG.

 - destination-y for exported headers is supported in Kbuild files
   again.

 - depmod is called with -P $CONFIG_SYMBOL_PREFIX on architectures that
   need it.

 - CONFIG_DEBUG_INFO_REDUCED disables var-tracking

 - scripts/setlocalversion works with too much translated locales ;)

* 'kbuild' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild:
  kbuild: Fix reading of .config in link-vmlinux.sh
  kbuild: Unset language specific variables in setlocalversion script
  Kbuild: Disable var tracking with CONFIG_DEBUG_INFO_REDUCED
  depmod: pass -P $CONFIG_SYMBOL_PREFIX
  kbuild: Fix destination-y for installed headers
  scripts/link-vmlinux.sh: source variables from KCONFIG_CONFIG
  kernel: Replace timeconst.pl with a bc script
  mod/file2alias: make modalias generation safe for cross compiling
