    iproute2: split iproute2 configure and compile logic
    
    Previously we relied on the iproute2 makefile automatically running the
    configure script on first run. This does not allow control of some
    configure options, or of when the configure script is re-run.
    
    The motivating usecase here is ./configure --color=auto, though that is
    not implemented in this commit.
