My original request to work on a GCC-based solution rather than exporting 
the extra names from libmvec.so was *not* meant to mean "post one message 
to the gcc list and expect a solution to emerge and be implemented".  It 
was meant to mean leading the full process from discussion through 
consensus building and implementation.  (And originally we envisaged that 
the asm-based workaround in the header would suffice, before it turned out 
that didn't work with LTO.)
