With CONFIG_LTO enabled the current way of extracting the configured environment no longer works, i.e. the object file content changes due to LTO.
Build a host tool which prints the configured environment instead of using objcopy and friends to achive the same.
The code and Makefile changes were mostly stolen from tools/env/ i.e. the target userspace tools to access the environment.
Changes in v2: - reworked to build a host tool which prints the configured environment as proposed by Pali Rohár https://lore.kernel.org/u-boot/20221018174827.1393211-1-max.oss.09@gmail.com... - renamed patch, v1 used "Makefile: fix u-boot-initial-env target if lto is enabled"
