when $target is a path relative to $objtree the script fails.
This is because we cd to $basedir and then copy to $tempdir which
then is no longer valid. Fix this by converting $tempdir to an
absolute path first.

If barebox is builded out-of-tree we don't find the autogenerated
autoconf.h because we search in the srctree.
With this patch we don't get this error message:

The basic console used for USBboot has two different formattings,
one for text coming from the host and another for text coming from
the target.
This change makes both formattings readable regardless of the
console background color.

DFU is for device firmware upgrade, but for development purposes it's
sometmes useful to just start a kernel vie DFU. This adds a boot option
for doing this and also the corresponding counterpart on the host. With
this it's possible to boot a system with:
scripts/dfuboot.sh -k linuximage -d dtb -c "root=ubi0:root ubi.mtd=ubi rootfstype=ubifs ignore_loglevel"

This adds a target to generate environment files from directories.
These are compiled into the barebox binary.
use it as:
bbenv-$(CONFIG_SOMETHING) += my-environment
The directory containing the files to compile into the binary
should be named my-environment.
This can be accessed in C code later as:
extern unsigned char __bbenv_my_environment_start[];
extern unsigned char __bbenv_my_environment_end[];

Finding out whether to rebuild the environment is a difficult task
since we have to track all files in a directory. Instead of trying
this, just rebuild the environment during every build and only if
it differs to the last one overwrite the target. This way make
only sees a change when the environment is changed.

This adds a tool for installing kernels according to the bootloader
spec. systemd already has a similar tool, but it is limited to installing
kernels on the currently running system. The barebox kernel-install
tool instead can also be used to install kernels on removable media on a
development host for cross development. It is compiled in two variants,
as 'kernel-install' for the host and as 'kernel-install-target' using
$CROSS_COMPILE.

The Altera SoCFPGAs expect a simple header for their first stage
loaders. This adds a tool to generate images for the SoCFPGAs. The
header is either embedded into the image or optionally prepended
to the image. In this case code is added to jump over the image
header.
