    s390: Fix Enable VDSO for static linking
    
    The commit 5e855c8954014bca7b0d6f07312ec09553695ffd
    "s390: Enable VDSO for static linking" removed the definition of VDSO_SETUP
    which leads to not setup the vdso symbols.
    Instead it jumps to false addresses.
    
    This patch just re adds the removed VDSO_SETUP macro definition.
    
    ChangeLog:
    
    	* sysdeps/unix/sysv/linux/s390/init-first.c (VDSO_SETUP): New define.
