[Bug target/33755] Gcc 4.2.2 broken for mips linux kernel builds

[daney at gcc dot gnu dot org]

It appears to be a GCC bug not binutils:

If you look at the assembly output for gcc-4.2, we emit:

    lui     $2,%hi($LC6)

But there is no corresponding %lo($LC6) to be found.  No amount of relocation
sorting could overcome this problem.

The corresponding printk calls are also missing.  Very strange.

This is fixed in 4.3.
