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 ;)
