    misc/vfc: fix build on armv7
    
    Supply -mfpu=neon-fp16 in CXXFLAGS to permit use of half-precision
    floats in NEON code.  This is supported by armv7 devices as early as
    the Raspberry Pi 2, but excludes armv6 devices (these don't have NEON).
    
    Approved by:    portmgr (build fix blanket)
