Use VFPv3-D16 FPU for ARM builds

Upstream-Bug: https://ghc.haskell.org/trac/ghc/ticket/5914
Launchpad-Bug: https://ghc.haskell.org/trac/ghc/ticket/5914

Jani writes: The D16 part was Debian/Ubuntu specific, IIRC we define hardfloat
in that particular variant (16 double registers) or we had a different naming
for some reason.

Gbp-Pq: Name ARM-VFPv3D16
