environment generation: Fix dependencies ...

The dependencies for generating the environment do not work properly:

- If files are removed from the defaultenv, a subsequent make will not
  update the default environment.
- If CONFIG_DEFAULT_ENVIRONMENT_PATH changes, the default environment
  also will not be regenerated.

This patch fixes this by introducing a cmd_env which has the content of
$(ENV_FILES) in the command so that the if_changed mechanism recognizes
a change when $(ENV_FILE) changes. This also results in a nice "  ENV "
string in the build process.

kbuild: keep the barebox binary accessible ...

When building a special image  from the original (compressed or
not) binary, to not overwrite KBUILD_BINARY.

This allows producing multiple images (such as MLO, UBL, ...)
from the (z)barebox.bin. In the case where no special image is
used, KBUILD_IMAGE is set to KBUILD_BINARY.

This patch was developed together with Sascha Hauer. Thanks!

Makefile: generate a barebox-flash-image link ...

Depending on the SoC a barebox.bin, barebox.netx, barebox.s5p, MLO image
is generated. With pbl support there now is an additional
arch/arm/pbl/zbarebox.bin image.

To help the user to determine which image should be flashed to his device,
generate a barebox-flash-image link.

Add pre-bootloader (pbl) image support ...

This allows for creating a pre-bootloader binary for
 - nand boot
 - mmc boot
 - compressed image

The pbl will be incharge of the lowlevel init if needed.
The barebox will skip it.

Import string functions from linux 3.4 (arch/arm/boot/compressed/string.c) and
implement a dummy panic.

For now on introduce dummy zbarebox* targets and c code that will contain later
the decompressor. This only implemeted on ARM.

This patch is based on Sascha Hauer <s.hauer@pengutronix.de>

kbuild: add pre-bootloader (pbl) target ...

This will allow to link compiled object to the built-in-pbl.o across the source
tree that will be finally link to the pbl.

Now we compile the source %.c in pbl-%.o and provide -D__PBL__
so we can known in the source when it's compile for barebox or the pbl.

Makefile: update barebox version if CONFIG_KALLSYMS is not set ...

If CONFIG_KALLSYMS is not set then barebox version is always "#0".
By-default on mips boards CONFIG_KALLSYMS don't set, so barebox
version does not increase after every build.
This patch fixes the problem.

The bareboxenv-target binary is automatically created but never

the situation by adding scripts/bareboxenv-target to .gitignnore

in the core Makefile.

Makefile: fix build timestamps ...

This patch adds the scripts/mkcompile_h from the Kernel. This gives
us additional information about the build like who built this binary
and with which compiler. Currently the only information used is the
build timestamp and the generation number.
This also fixes the build timestamp in the banner which is now correct
even with consecutive builds without making clean in between.
