toolchain: Improve C library option selection
Turn BR2_LARGEFILE, BR2_INET_IPV6, BR2_INET_RPC, BR2_USE_WCHAR, BR2_ENABLE_LOCALE and BR2_PROGRAM_INVOCATION into hidden options. Then, for Buildroot toolchains, external toolchains and Crosstool-NG toolchains, provide visible options that selects the hidden options. This allows : * To show a different label and help text in the case of Buildroot toolchain (do you want to enable feature X ?) and in the case of external toolchain (is feature X available in your toolchain ?) * To not show any option when a glibc external toolchain is selected (since glibc is assumed to support all of largefile, IPv6, RPC, WCHAR, locale and program invocation) and have them all selected in that case. There is some amount of duplication between Buildroot toolchain config options and Crosstool-NG toolchain config options, because kconfig doesn't allow to source the same Config.in file twice (even if under mutually exclusive conditions). This duplication is more readable that the hack that consists in splitting files in multiple pieces. However, this commit changes the name of the options visible in the configuration interface, so existing .config files will have to be updated accordingly.
