Hi,

I don't know if this count as a test but it seems that both FreeBSD and
NetBSD also called it "gls" in their respective packages:

https://cgit.freebsd.org/ports/tree/sysutils/coreutils/pkg-plist
http://cvsweb.netbsd.org/bsdweb.cgi/pkgsrc/sysutils/coreutils/PLIST?rev=1.22&content-type=text/x-cvsweb-markup

But, I have to say that I still don't understand why you would not also
consider applying my patch.
