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
