Thanks, the strange thing in my case is the iMX6 is cortex-A9, but I had 
to step back to
cortex-A8 in menuconfig for this to work.
I did notice that when I use A9 vs A8, the floating point settings 
automatically change
in menuconfig.  I *thought* A8 & A9 were the same from that standpoint, 
but not really
sure.  Anyway, I plan to spend at least the next few days looking into 
this, so hopefully I'll
have more information soon.
