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
