	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.

2010-12-08	ccache: rework ccache management	Thomas Petazzoni
	* ccache is now a normal package (both for the host and the target). * ccache option is now part of the "Build options" menu. It will automatically build ccache for the host before building anything, and will use it to cache builds for both host compilations and target compilations. * bump ccache to 3.1.3 Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
2010-07-28	toolchain: remove multilib	Thomas Petazzoni
	Supporting multilib is much more than just passing --enable-multilib to gcc. You have to actually build the C library several times (once for each multilib variant you want to support in your toolchain), and to pass MULTILIB_OPTIONS/MULTILIB_EXCEPTIONS values to gcc to let it know the set of multilib variants you're interested in. Since we'll probably never support multilib toolchains in Buildroot, just get rid of this BR2_ENABLE_MULTILIB option. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

	Handle the internal toolchain backend mechanism the same way we handle other backends. Signed-off-by: Yann E. MORIN <yann.morin.1998@anciens.enib.fr> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
