I just added this some days ago in order to give debug information for a a 
bug in strigi I had reported. I forgot to take it out, but so far only few 
packages were compiled with this setting. But thanks for mentioning this, 
I removed the debug setting now.
But should it matter? Optimization still happens. And when these 
interrupts hapen, the CPU is not at 100%.

I do not use march=native because I sometimes use another host with 
distcc.
