Just a comment. What do you suggect we put in the Linux kernel source?
Please keep in mind that the same kernel source is used by different
people with different versions of gcc/binutils. The current binutils
breaks the Linux kernel in 2 ways:

1. The command line is not compatible with the previous version. That is
"-m4100 -mips2" is not allowed any more.
2. It won't generate a working kernel no matter what you do.

I don't believe the binutils should break the existing Linux kernel
source. Chris's solution is ok by itself. But I don't think it is the
right solution for Linux.
