[polly][cmake] patch to build monolithic shared library

[David Fang]

Hi,
 	I've recently refreshed my patch to link polly as a single shared 
lib.  This was in response to the original report at:
http://llvm.org/bugs/show_bug.cgi?id=14833

Live patch:
https://github.com/fangism/polly/compare/master...shared-lib-patch.diff

I don't really know whether a single shared-lib is preferred over 
sub-libraries.  This was intended as a workaround, but if parties are 
interested, this patch could be cleaned up.

David
