  It is still possible to add an _AVAILABLE for sub-options that need them.
For something like a python module, it does make sense have an _AVAILABLE
for the sub-option.  Similar for GStreamer modules using an external library.
These things can be considered a separate (micro)package, in some sense.

  If the script converts the python-dpkt example above into
	depends on BR2_PACKAGE_PYTHON_ZLIB_AVAILABLE
	select BR2_PACKAGE_PYTHON_ZLIB
won't kconfig detect that PYTHON_ZLIB_AVAILABLE doesn't exist?  Then it
will be easy enough to fix those suboptions manually (if there aren't too
many of them...).
