linux-next: build failure after merge of the final tree (Linus' tree related - powerpc)

Hi all,

After merging the final tree, today's linux-next build (powerpc
allyesconfig) failed like this:

<stdin>:1:0: error: -mcall-aixdesc must be big endian
<stdin>:1:0: error: -mcall-aixdesc must be big endian

Caused by commit 7c105b63bd98 ("powerpc: Add CONFIG_CPU_LITTLE_ENDIAN
kernel config option").

I have reverted that commit for today.

Urgh, allyesconfig is building an LE kernel. Ian: do we need to reverse
the polarity of the option, and call it CONFIG_CPU_BIG_ENDIAN?

More or less. See what we did with PPC_WERROR, for the same reasons, so
that it was off for an allyesconfig.

    config PPC_DISABLE_WERROR
            bool "Don't build arch/powerpc code with -Werror"
            default n
    
    config PPC_WERROR
            bool
            depends on !PPC_DISABLE_WERROR
            default y
