The TQM may be a good choice for a model, or may be not. It  dopeneds
onthe hardware. It is not possible to give a general recommendation.

No  such  change  is  necessary  nor  encouraged.  Just  export   the
CROSS_COMPILE envrionment variable as needed.

Don't forget to make sure to use the correct definition of bd_info.

A  much  better  and  less  intrusive  way  is  to  copy  .config  to
arch/ppc/configs/<boardname>_defconfig  so  you  can use the standard
"make <boardname>_config ; make oldconfig ; make dep ;  make  uImage"
command sequence.
