[PATCH] udev spec file bits

[PATCH] udev spec file bits

Some spec file changes.  Primarily, this makes the thing build without a
build root if so desired (i.e. build right out of /usr/src/redhat and
the standard file system).  It should still build from a build root,
too.

Also:

	- Add some Prereqs
	- Pass RPM_OPT_FLAGS to make so we build with the RPM build
	  policy (i.e., optimizations, architecture, etc.)
	- Specify the exact files in %files to make sure we install
	  everything properly and avoid a warning
