toolchain-crosstool-ng: use the Crosstool-ng config options instead of the common hidden ones

Since we are some day going to finally rename the badly named common
toolchain options (BR2_USE_WCHAR, BR2_ENABLE_LOCALE, BR2_INET_RPC,
etc.) into something more logical, let's start using the Crosstool-NG
toolchain options in the Crosstool-NG code.
