[Buildroot] [PATCH 3/4] target/initramfs: actually build initramfs target

[Jeremy Kerr]

Currently, BR2_TARGET_ROOTFS_INITRAMFS doesn't actually do anything,
as it doesn't alter $(TARGETS)

This change hooks up the TARGETS variable to INITRAMFS_TARGET (which
is only set if BR2_TARGET_ROOTFS_INITRAMFS=y), so that the initramfs
list is built.

[Buildroot] [PATCH 2/4] package/udev: fix CFLAGS for udev extras

[Jeremy Kerr]

If the udev extras are built without large file support in uClibc,
I get the following error:

 build_powerpc/staging_dir/usr/bin/powerpc-linux-uclibc-gcc -c -g -Wall
 -pipe -D_GNU_SOURCE -D_FILE_OFFSET_BITS=64 -Wstrict-prototypes
 -Wsign-compare -Wshadow -Wchar-subscripts -Wmissing-declarations
 -Wnested-externs -Wpointer-arith -Wcast-align -Wsign-compare
 -Wmissing-prototypes -Os ext.c -o ext.o
 In file included from build_powerpc/staging_dir/usr/include/stdio.h:28,
 from ext.c:19:
 build_powerpc/staging_dir/usr/include/features.h:382:4: error:
 #error It appears you have defined _FILE_OFFSET_BITS=64. Unfortunately,
 uClibc was built without large file support enabled.

Although the base udev package builds correctly, the extras pacakges
don't adjust their CFLAGS depending on BR2_LARGEFILE.

This change adds the required CFLAGS modifications to make the
extras build.

[Buildroot] [PATCH 1/4] package/udev: fix dependency for scsi_id

[Jeremy Kerr]

According to udev.mk, the scsi_id package depends on the libvolume_id
library, so add this dependency to Config.mk

[Buildroot] [PATCH 4/4] package/udev: create base device nodes after mounting a new /dev

[Jeremy Kerr]

Currently, udev won't start for me, as we've just mounted a new /dev,
which is completely empty, and udevd requires a /dev/null.

This change manually creates the three base device nodes (zero, null
and console) so that udev can start.
