    xen/build: use the correct kconfig makefile
    
    This resolves the following observed error during config merge:
    
      /bin/sh /path/to/xen/xen/../xen/tools/kconfig/merge_config.sh -m .config 
/path/to/xen/xen/../xen/arch/arm/configs/custom.config
      Using .config as base
      Merging /path/to/xen/xen/../xen/arch/arm/configs/custom.config
      #
      # merged configuration written to .config (needs make)
      #
      make -f /path/to/xen/xen/../xen/Makefile olddefconfig
      make[2]: Entering directory '/path/to/xen/xen'
      make[2]: *** No rule to make target 'olddefconfig'.  Stop.
      make[2]: Leaving directory '/path/to/xen/xen'
      tools/kconfig/Makefile:95: recipe for target 'custom.config' failed
    
    The build was invoked by first doing a defconfig (which succeeded):
    
      $ make -C xen XEN_TARGET_ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- 
defconfig
    
    Followed by the config fragment merge command (which failed before this 
patch)
    
      $ cat > xen/arch/arm/configs/custom.config <<EOF
      CONFIG_DEBUG=y
      CONFIG_EARLY_PRINTK_ZYNQMP=y
      EOF
      $ make -C xen XEN_TARGET_ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- 
custom.config
