[XEN PATCH v2 08/29] tools/hotplug: cleanup Makefiles

[Anthony PERARD <anthony.perard@xxxxxxxxxx>]

Remove "build" targets.

Use simply expanded variables when recursively expanded variable
aren't needed. (Use ":=" instead of "=".)

Don't check if a directory already exist when installing, just create
it.

Fix $(HOTPLUGPATH), it shouldn't have any double-quote.

Some reindentation.

FreeBSD, "hotplugpath.sh" is already installed by common/.
