Why are you asking here if you should submit a bug report on your compiler? This is not a bug in R, but in your compilation enviroment.
If you update your compiler you may well need to reinstall R -- you did not mention that you did so. BTW, R is not setting '-mcpu=i686 -pipe', but your Linux distro may be.
