[XEN PATCH 25/57] tools/examples: cleanup Makefile

[Anthony PERARD <anthony.perard@xxxxxxxxxx>]

Don't check if a target exist before installing it. For directory,
install doesn't complain, and for file it would prevent from updating
them.

Remove XEN_CONFIGS-y which isn't used.

Remove "build" target.

Add an empty line after the first comment. The comment isn't about
$(XEN_READMES), it is about the makefile as a whole.
