You can always run generated binaries on an emulator or a target board
for testing. I have cross compiled a lot of code using gcc and have yet
to see wrong binaries caused by cross compiling versus native compiling.
I could imagine problems with floating point expressions evaluated at
compile time and resulting in slightly different results. 
The only way to see if cross compiling generates wrong binaries, is to
try it and evaluate the results.

We will probably need both as some build scripts run generated code.
