Subject: [PATCH] kconfig: qconf: use if_changed for qconf.moc rule
Regenerate qconf.moc when the moc command is changed.
This also allows 'make mrproper' to clean it up. Previously, it was
not cleaned up because 'clean-files += qconf.moc' was missing.
Now 'make mrproper' correctly cleans it up because files listed in
'targets' are cleaned.
