This will sort the default environment file generated by "make u-boot-initial-env", but won't sort the default environment in the compiled u-boot binary. The file u-boot-initial-env is considered to use for the userpace environment access tools [1] in case of that the environments is written the first time into its location. This is done on the one hand for a better overview and comparison of the generated environment file. On the other hand it is to synchronize the output with the script get_default_env.sh, which generated a sorted default environment file. The sorting preserves the order of equal variable names by sorting only the variable name, and disable the last-resort comparison. After sorting, unnoticed blank lines at the end move to the top. Avoid that by removing it before sorting.
