minifs: New way of locating config files/dirs

MINIFS_BOARD can now contain extra components, also, config
files are searched for in quite a few other directories.
For example an armv6 board can have it's config file in
conf/board/<board>/
conf/arch/arm/
conf/arch/armv6/
Also the notion of "role" appears, and it will look for files and
packages in
conf/distro/.../
