[PATCH] MIPS: Kbuild: remove -Werror

MIPS does not build with the standard W=1 Kbuild switch with - tested with
gcc-4.6 by me and gcc-4.5 by John Crispin. The reason is that MIPS adds
-Werror build option.

This patch removes the option to make W=1 work. I do compile-tests for various
architecture before accepting MTD patches and I have scripts which build before
applying the patch, then after, and then compare 2 build logs and report about
new warnings. I use W=1 to see more warnings in the logs diff. And from my
perspective all platforms should build with W=1.

The other way would be to fix all warnings, but there are false positives, and
it is too difficult to maintain the code warning-free, so it is easier to just
remove -Werror.
