Did you try doing a "make clean" before building the kernel? I believe
I've sometimes had problems in the past with the following sequence:

 1. Build kernel from sources
 2. Upgrade gcc and/or binutils
 3. Make minor change to kernel .config file
 4. Do a "make" of the kernel

If you do a make clean between 3 & 4, it seems to avoid problems
caused by doing a build with "mixed" gcc or binutils versions.
