 So I have committed this change now, thanks for your review.  I'll think 
of something cleverer in place of this -march=from-abi option as time 
permits; fortunately it's greppable, so easily replaced.

 I've been wondering if these extra vectors were added by mistake instead, 
like slipped through in a larger commit unnoticed.  I'll post a fix to the 
BFD64 block separately.

 My understanding is it only really matters for hosts that do not have a 
64-bit integer type and therefore cannot handle 64-bit quantities.  In 
which case I couldn't care less, GCC has supported 64-bit long long on 
32-bit hosts since time immemorial and the last teething problems in this 
area I seem to remember went away in late 1990s.
