Not necessary.

This patch adds,
- support more CPU variants other than MIPS 4K
- without changing the code.

In other words, every U-Boot/MIPS user other than MIPS 4K must change
cpu/mips/config.mk as he wants.

I thought this patch is more beneficial for MIPS users even if breaking
old gcc 2.96 support. That's all.

I don't want to argue with you about this issue. If you disagree, I'll
drop this from my queue. I don't mind, I can live without this change.
