We could, but you sent a patch that uses sed instead ;)

I'm fine with using dos2unix. I thought you were doing so to avoid
adding another dependency to the barebox build system. In the end
this script is not even part of the build system, but only a helper
script which is called manually, so this shouldn't be a problem.
Also unix2dos/dos2unix is likely found in all Linux distributions. Just
go for it.
