[PATCH] Makefile: Sort u-boot-initial-env output

[Christoph Niedermaier]

For a better overview and better comparison sort the initial
environment as the get_default_env.sh script does. We need
to preserve the order of equal variable names. So only sort
by the variable name, and disable the last-resort comparison.
Also remove blank lines before sorting.
