2.8.0 can't be extracted by tar on macOS 10.14 and older

/usr/bin/tar fails to extract the release tarball with this message:

tar: Ignoring malformed pax extended attribute
tar: Error exit delayed from previous errors.

Installing a recent libarchive and using its tar is an effective workaround, but it would be nice if it wasn't necessary. Extracting with GNU tar (on a different system in this example) sheds a little more light on what the problem is:

/usr/bin/gnutar: Ignoring unknown extended header keyword `LIBARCHIVE.xattr.com.apple.metadata:kMDItemTextContentLanguage'
/usr/bin/gnutar: Ignoring unknown extended header keyword `SCHILY.xattr.com.apple.metadata:kMDItemTextContentLanguage'

The issue is reproducible on linux, too:

$ rpm -q tar
tar-1.23-15.el6_8.i686

$ tar xf SDL2_image-2.8.0.tar.gz
tar: Ignoring unknown extended header keyword `LIBARCHIVE.xattr.com.apple.metadata:kMDItemTextContentLanguage'
tar: Ignoring unknown extended header keyword `LIBARCHIVE.xattr.com.apple.metadata:kMDItemKeyphraseVersion'
tar: Ignoring unknown extended header keyword `LIBARCHIVE.xattr.com.apple.metadata:kMDItemKeyphraseLabels'

This is fixed for 2.8.1, thanks!
