Thanks for your suggestion. How do I do that properly?
I think the following will not work, because changing CC will cause
arch/ia64/kernel to be rebuild, right?
# make -C arch/ia64/kernel CC=gcc-4.7.3
# make CC=gcc-4.5.4

And what would you suggest to add after ia64/kernel and ia64/mm? I do
not know much about the parts of the kernel that run at this early
stage.
