What is the reason for not using it ? hard float is ABI level decision, if your system is running base OS with hard float turned on you dont have this choice to not use it
if you are using SDK environment then please use $CC variable and its ilk to get it right set of options to compile the application and good thing is that when you turn
this into a bitbake recipe to build the app it will still work.
