This implements two new options for the loadenv command:
-s: removes (scrubs) old directory contents to be able to
create a fresh environment from for example /dev/defaultenv
-n: no overwrite. Do not overwrite existing files. This allows
to keep parts of the old environment.

Since the utility outputs the image on stdout we have to print the
error messages to stderr in order to see them.

The omap spi utility requires the image size to be a multiple of four
bytes. This seems unnecessary, we can just pad with a few bytes to
get the required alignment.

Booting from SPI on an AM35xx (and possibly other TI SOCs) requires
a special format:
- 32 bit image size in big-endian
- 32 bit load address in big-endian
- binary image converted from little- to big-endian
The mk-am35xx-spi-image tool converts barebox.bin to
this format.

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.

The call if_changed mechanism does not work when the command
contains backslashes. This basically is an issue with lzo
and bzip2 compressed kernels. The compressed binaries do not
contain the uncompressed image size, so these use size_append
to append the size. This results in backslashes in the executed
command. With this if_changed always detects a change in the
command and rebuilds the compressed image even if nothing
has changed.
Fix this by escaping backslashes in make-cmd
This was worked out together with Jan Lübbe. The same patch
has recently been accepted to the kernel.

Now we compile the source %.c in pbl-%.o and provide -D__PBL__

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.
