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.
