commit c6f2c531ed47d2604a7227530f3c7c703e1c4e8b Author: Patrick Georgi patrick@georgi-clan.de Date: Sun May 10 18:00:05 2015 +0200
kconfig: handle globbed files backwards
They're essentially collected on a stack before they're parsed. So we push them backwards, then parse them in the correct order.
