[PATCH 2/8] gnu: Use define-public to export packages.

[David Craven <david@craven.ch>]

* gnu/packages/bison.scm (bison): Define public.
* gnu/packages/flex.scm (flex): Define public.
* gnu/packages/pulseaudio.scm (libsndfile, libsamplerate, pulseaudio): Define
public.
* gnu/packages/sdl.scm (sdl, sdl2, libmikmod, sdl-gfx, sdl-image, sdl-mixer,
sdl-net, sdl-ttf): Define public.
* gnu/packages/search.scm (xapian): Remove unnecessary #:export.
* gnu/packages/swig.scm (swig): Define public.
