#     powerpc: Add config fragment for disabling -Werror
#     
#     This makes it easy to disable building with -Werror:
#     
#       $ make defconfig
#       $ grep WERROR .config
#       # CONFIG_PPC_DISABLE_WERROR is not set
#       CONFIG_PPC_WERROR=y
#     
#       $ make disable-werror.config
#         GEN     Makefile
#       Using .config as base
#       Merging arch/powerpc/configs/disable-werror.config
#       Value of CONFIG_PPC_DISABLE_WERROR is redefined by fragment arch/powerpc/configs/disable-werror.config:
#       Previous value: # CONFIG_PPC_DISABLE_WERROR is not set
#       New value: CONFIG_PPC_DISABLE_WERROR=y
#       ...
#     
#       $ grep WERROR .config
#       CONFIG_PPC_DISABLE_WERROR=y
