    x86/shim: Fix parallel build following c/s 32b1d62887d0
    
    Unfortunately, a parallel build from clean can fail in the following manner:
    
      xen.git$ make -j4 -C tools/firmware/xen-dir/
      make: Entering directory '/local/xen.git/tools/firmware/xen-dir'
      mkdir -p xen-root
      make: *** No rule to make target 
'xen-root/xen/arch/x86/configs/pvshim_defconfig', needed by 
'xen-root/xen/.config'.  Stop.
      make: *** Waiting for unfinished jobs....
    
    The rule for pvshim_defconfig needs to depend on the linkfarm, rather than
    $(D)/xen/.config specifically.
