Switch gen-kconfig to new framework Also: - Move companion_* to comp_* to match the kconfig symbols - Replace bootstrap with former gen-versions.sh - Fold *.in.2 into their respective first parts; this moves common options to the end - if it is undesirable, inclusion of *.in can be moved where *.in.2 used to be (but that will also move version selection after common options). - Retire addToolVersion.sh (may later replace with a more comprehensive script that tries to download the added tarballs, copy the patches and try to apply them, and create a version.desc).

# musl second-part option
libc/musl: add musl-libc support This patch adds initial support for musl-libc. Musl-libc versions currently supported: * 1.0.3 (Stable) * 1.1.3 (Previous Mainline) * 1.1.4 (Mainline) Futher improvements are needed. * gcc-4.9.x has issues (Might be fixed in musl-1.1.4). * Multilib support is needed. * Checks to make sure paths are correct. * Move to 2-step gcc build. 3-step build is not necessary. Signed-off-by: Bryan Hundven <bryanhundven@gmail.com> [yann.morin.1998@free.fr: removed the gcc musl patch, to be added later; removed dead code do_get_arch()] Signed-off-by: "Yann E.

## depends on ! WINDOWS && ! BARE_METAL
musl: config is broken for !EXPERIMENTAL If EXPERIMENTAL is not set, the only choice for version is the set of released versions - currently, 1.1.14. But this only option is disabled because it is also marked EXPERIMENTAL; this leaves no available choices in the configuration. Marking MUSL as experimental: it seems to have header issues which prevent, for example, gdbserver from building. musl copied chunks of ptrace.h code from the kernel into its own headers, which now clash with Linux kernel headers. Manifests at least on SH4 target. Also, musl breaks in powerpc builds: GCC balks at it with "unsupported DEFAULT_LIBC" message. Also, 64-bit powerpc and mips are not supported. So, until someone figures out the dependencies for musl in config/, mark it experimental. Signed-off-by: Alexey Neyman <stilor@att.net>

## select LIBC_SUPPORT_THREADS_NATIVE
gcc: Build static libgcc in core_pass1 Per https://github.com/crosstool-ng/crosstool-ng/issues/808 build static libgcc in the first pass which lets us skip the second one. Building mingw-w64 requires header files in order to build C++ support so mingw builds core pass 2. This could probably be cleaned up by splitting libc_start_files into a separate libc_header step. But for now having core 2 for mingw-w64 and core 1 for the other libcs will have to do. Anything that previously selected CC_CORE_PASSES_NEEDED now selects CC_CORE_PASS_1_NEEDED. The same goes for CC_CORE_PASS_2_NEEDED with the exception of mingw-w64. Fixes #808 Fixes #217 Signed-off-by: Chris Packham <judge.packham@gmail.com>
