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 v4:
- add '(objtree)/' when calling the tool. Suggested by Pali Rohár.
- renamed patch, as more than just the Makefile has changes
Changes in v3:
- moved the tool from scripts/ to tools/. Suggested by Tom Rini
- changed the dependencies to '$(env_h)' and 'tools'.
Suggested by Tom Rini and Pali Rohár.
- removed the sed rule which replaces \x00 with \x0A as this is already
done by the tool. Suggested by Pali Rohár.
Changes in v2:
- reworked to build a host tool which prints the configured
environment as proposed by Pali Rohár
