Add the patches with real changes from the binutils 2.39 stable branch. I am not aware that we ran into any of these problems, but I think it is better to take the existing stable patches. They were exported like this: git format-patch binutils-2_39...origin/binutils-2_39-branch I removed the patches changing the version numbers only. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
