If flex is available, ar links to it (not required, but if binutils  
finds it, it'll link to it):

If the host has flex library installed, binutils in cross-tools will  
link to static or shared flex library, as well.

I don't know what functionality that adds for ar when creating,  
extracting, and modifying archives.

If flex library isn't there, ar won't link to it.

That is what I was getting at. You may not see it if you don't have  
flex on the host, in temp system, or final system before binutils.

As for M4, we can move m4 before flex and bison, as well, or use M4=4  
during bison and flex configure.

Sincerely,
