To be honest I don't understand your problem.

You compile with hard float, you don't have a floating point unit, you enable a 
kernel feature + debugging to fixup the mess.

Your options:
	- Move to VFP and an arm core that has that
	- Disable NWFPE and implement fixed point integer arithmetic for JavaScript
	- Build your gcc with -msoft-float to automatically use Nicola's fixed point 
integer code for every operation...

what am I missing?
