initramfs: fix boot with dynamic /dev Devtmpfs (which is used by devtmpfs/mdev/udev options) doesn't get automounted by the kernel when an initramfs is used, causing boot failures when a dynamic /dev is used. Fix it by adding a pre-init script to mount devtmpfs before running init.

linux: remove support of linux26-* targets The linux-* mirror targets of linux26-* have been added a very long time ago (2010) and linux 2.6 is now considered 'old' anyway. It no longer makes sense to support these linux26-* targets, so this patch removes them. This is a simplification introduced in preparation of the kconfig-package infrastructure.

fs/initramfs: fix initramfs support On commit a24877586a566e052897e50e6a0c2f53cfb029f TARGETS_ROOTFS was introduced, however fs/initramfs/initramfs.mk was never updated, hence a show-targets would be rootfs-initramfs with rootfs-cpio afterwards hence never rebuilding the kernel with a proper cpio archive since TARGETS is always before rootfs-* as stated in the commit description.
