It's an external which lives in gstcheck.c. Redeclaring it makes some
compilers/architectures think the 'buffers' in the individual tests are
a different symbol... and therefore we end up comparing holodecks with
oranges.
Original commit message from CVS:
* gst/equalizer/Makefile.am:
* gst/spectrum/Makefile.am:
Fix includes order
* tests/check/Makefile.am:
Exclude v4l2src from the states test - it takes too long to start.
* tests/check/elements/spectrum.c:
Make the test run properly with CK_FORK=no

* gst/spectrum/gstspectrum.h:
Port GstSpectrum to GstAudioFilter and libgstfft, add support
for int32, float and double, use floats for the message contents,
average all FFTs done in one interval for better results, use
a better windowing function, allow posting the phase in the message
and actually do an FFT with the requested number of bands instead
of interpolating.
* tests/check/elements/spectrum.c: (GST_START_TEST),
(spectrum_suite):
Improve the units tests by checking for a 11025Hz sine wave
and add unit tests for all 4 supported sample types.
