Yes, this is definitely not correct.  The flag "text" being set tells
Git to do line-ending conversion and "eol=lf" says to convert line
endings into LF.

You should look for things in your .gitattributes file that say
something like "* text", which you probably don't want.  You could use
"* text=auto", which should be fine for most cases, though.  It's also
possible those aren't in a .gitattributes file in your repository but
one elsewhere on your system.  You can check gitattributes(5) for the
locations of other files that can affect it.

As a note, it is best practice not to check binary dependencies or build
artifacts into the repo.  Those are best stored elsewhere, such as an
artifact server.
