[Cin] executable stacks are bad...m-kay?

[Phyllis Smith]

Rob, Andrew:
Although I was able to build with Andrew's patch and loaded/played a video
with audio file, I am quite concerned that there will be fallout from this
patch.  I will need to do a lot more tests of many various aspects to  make
sure there is no impact and that will take me some time.  But very willing
to start tomorrow as I have always want to Quality Control test suite and
this would be a good opportunity to create one.  As usual I might not
succeed in doing so due to interruptions.

The good news is that this may just have been written that way in the
cinelerra/Makefile without any real thought put into options once it was
working!  Stay tuned.
