libsupc++ is the GNU implementation.  libcxxrt is what we ship on FreeBSD.  
libc++abi exists because of some annoying NIH from Apple.

I believe that libc++abi is does not implement support for foreign exceptions 
(though this may have been fixed recently).  The correct fix for this is 
probably to persuade Android to ship libcxxrt instead of libc++abi.
