powerpc: Add configurable -Werror for arch/powerpc
Add the option to build the code under arch/powerpc with -Werror. The intention is to make it harder for people to inadvertantly introduce warnings in the arch/powerpc code. It needs to be configurable so that if a warning is introduced, people can easily work around it while it's being fixed. The option is a negative, ie. don't enable -Werror, so that it will be turned on for allyes and allmodconfig builds. The default is n, in the hope that developers will build with -Werror, that will probably lead to some build breaks, I am prepared to be flamed. It's not enabled for math-emu, which is a steaming pile of warnings. Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

9 This option tells the compiler NOT to build the code under
10 arch/powerpc with the -Werror flag (which means warnings
11 are treated as errors).

13 Only enable this if you are hitting a build failure in the
14 arch/powerpc code caused by a warning, and you don't feel
15 inclined to fix it.
