I don't think the GCC bits are difficult, it's mostly a matter of making 
sure GCC knows what vector routines are available in glibc.  After that 
it should "just work".  The biggest worry I'd have would be ABI 
considerations -- ie, how are vector objects passed and returned from 
those routines.


Note that GCC is in its bugfixing phase until May, so we've got plenty 
of time.
