    diffutils: do_configure: fix "Argument list too long"
    
    Fixed when len(TMPDIR) =  410:
    aclocal: error: cannot open echo [snip]: Argument list too long
    
    This is becuase it has a lot of m4 files, use relative path for them
    can fix the problem.
    
    It doesn't happen when MACHINE="qemux86", I think it is because
    intel-x86-64 is longer than qemux86.
