    Fatal error when using cmake < 2.8.10 on ARM NEON
    
    Address issue #733: This makes the known issue of building VOLK for ARM 
NEON with
    CMake version < 2.8.10 a fatal error at cmake time, and gives a message to 
that effect.
    This is considered preferable to a linking error towards the end of the 
build.
