u-boot-tools: Fix reproducibility issue
If you build on a system with git < 2.14 from scratch (e.g. debian9), the tree will be marked as "dirty" and the version will include "-dirty", leading to a reproducibility problem. The issue is the inode count for Licnses/README changing due to do_populate_lic hardlinking a copy of the file. We avoid this by ensuring the index is updated with a "git diff" before the u-boot machinery tries to determine the version. build$ ../git/scripts/setlocalversion ../git "" build$ ln ../git/ build$ ln ../git/README ../foo build$ ../git/scripts/setlocalversion ../git ""-dirty (i.e. creating a hardlink dirties the index) (From OE-Core rev: a4de915af9e2c4d365527ad09286483b2ee904fc) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
