Wel, the main difference is  that  using  the  correct  CROSS_COMPILE
setting   also  makes  sure  you  are  linking  against  the  correct
libraries.

If you manually mess with the "-mcpu" options you may  generate  code
that does not fit what the libraries you're linking against expect.

Doing so is an excellent method to keep you  busy  for  a  long  time
debugging all kinds of "interesting" software problems.

Best regards,
