If u-boot is compiled with the LTO option, it is no longer possible to
use the script 'get_default_envs.sh'. The problem was already observed
and a solution available upstream u-boot since the commit 486aef08de09 [1].
This was first available in release v2023.04.
Now if the the new tool 'printinitialenv' is available it is used. The
tool is build with u-boot that is a dependency of this package.

The redirect is still broken here, this command line is not correct, as
it's not the same as it used to be.
