Change Log:
The target CFLAGS were getting mixed in during a manual build of some
omniorb pkg tools that could be viewed as host tools.
This manual build was a dirty workaround and created some bad
cornercases. So I converted the package over to actually using the
host pkg build and removed the need for a patch and custom mods in the build.

Also there wasn't a dependency on the target having python, just
host-python for performing the initial build.  So depends were adjusted
accordingly. If python bindings are required, they can be found in a different
package called omniORBpy.  The omniORB package only uses python for
the build process.

Fixed a bug with long double support.  Currently leaving it disabled
as most targets won't use it.  This allows greater toolchain compatibility.
