The default is to use hard float support, but not between libraries. So 
all your code will use hard float (mixed NEON and VFP instructions), 
it's only when passing floats to other libraries it uses the standard 
registers instead of the floating point stack to exchange the data. This 
usually has no impact on performance, unless in some very particular 
circumstances.
