More changes for initramfs and hw- targets with a base architecture.
The $BASE_ARCH approach didn't work because targets need to override things
like KERNEL_PATH, so they need to source the relevant details file themselves.
Shuffle things around so they can do that: move $CROSS into cross-compiler.sh,
add cross compiler to $PATH independently of that, remove $ARCH from CONFIG_DIR
and change users to add it, have getconfig check $ARCH_NAME directory first,
redo qemu_defaults to chop out initramfs options less uncleanly...
