toolchain: move buildroot config files 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>

# Config entries for internal toolchain backend
toolchain: use same gdb Config.in for internal/external toolchains We used to use different gdb configs for internal and external toolchains because mconf won't source the same file twice. This works, but is kind of sub optimal, as people forget to keep them in sync. Fix it to use the same file for both situations by shuffling around the config options a bit. Should work identical to before (except for the newer gdb versions available for ext).

config BR2_TOOLCHAIN_BUILDROOT_VENDOR
string "custom toolchain vendor name"
default "buildroot"
help
This option allows to customize the "vendor" part of the
toolchain tuple, where the toolchain tuple has the form
<arch>-<vendor>-<os>-<libc>. The default value, "buildroot",
is fine for most cases, except in very specific situations
where gcc might make different decisions based on the vendor
part of the tuple. The value "unknown" is not allowed, as the
cross-compiling toolchain might then be confused with the
native toolchain when the target and host architecture are
identical. The value can not be empty either.
If you're not sure, just leave the default "buildroot" value.

glibc: add 2.19 as a supported version glibc 2.19 has been released recently (https://sourceware.org/ml/libc-alpha/2014-02/msg00224.html). This commit allows to build a toolchain with this new version. In order to allow this, we add a version selection that did not exist for glibc. We default to 2.18, which was the only supported version until now, and add an option for 2.19. For microblaze, which uses a specific glibc version, the version selection choice is not displayed.

binutils: make it a proper package * Convert binutils to a proper autotargets package * Add version 2.21 and drop version 2.17 * Hook up packaged binutils for target gcc * Build tools are on HOST_DIR now so change it * Move cross/host gcc to HOST_DIR * Drop kludge from commit 3c77bab2eeace3ee675bd745ca335fa3dd1630bb This is fixed in the next commit "gcc: install copies of libgcc, libstdc++ and libgcj to the sysroot" - tested for arm & x86_64 targets. * TARGET_CROSS now pointed to HOST_DIR too [Peter: Config.in tweaks] Signed-off-by: Gustavo Zacarias <gustavo@zacarias.com.ar> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

toolchain: move elf2flt option inclusion to toolchain-buildroot/Config.in The only remaining thing in toolchain-buildroot/Config.in.2 is the inclusion of the elf2flt option. It doesn't really make sense to have a separate Config.in file for that, so let's move this to toolchain-buildroot/Config.in.

toolchain: use same gdb Config.in for internal/external toolchains We used to use different gdb configs for internal and external toolchains because mconf won't source the same file twice. This works, but is kind of sub optimal, as people forget to keep them in sync. Fix it to use the same file for both situations by shuffling around the config options a bit. Should work identical to before (except for the newer gdb versions available for ext).
