Recent kernel versions need toolchain in order to properly configure kernel, for example to set CC_HAS_ASM_GOTO config symbol, so missing toolchain leads to the following error while running `make kernel_oldconfig` on ath79 target with 4.19 kernel in the clean tree: init/Kconfig:17: syntax error init/Kconfig:16: invalid option ./scripts/clang-version.sh: line 15: mips-openwrt-linux-musl-gcc: command not found ./scripts/gcc-plugin.sh: line 11: mips-openwrt-linux-musl-gcc: command not found net/sched/Kconfig:44: warning: menuconfig statement without prompt make[4]: *** [scripts/kconfig/Makefile:69: oldconfig] Error 1 So in order to support this new kernel versions, this patch adds toolchain as a hard dependency to the kernel_*config targets.

This is the buildsystem for the OpenWrt Linux distribution.
To build your own firmware you need a Linux, BSD or MacOSX system (case
sensitive filesystem required). Cygwin is unsupported because of the lack
of a case sensitive file system.
You need gcc, binutils, bzip2, flex, python, perl, make, find, grep, diff,
unzip, gawk, getopt, subversion, libz-dev and libc headers installed.
1. Run "./scripts/feeds update -a" to obtain all the latest package definitions
defined in feeds.conf / feeds.conf.default
2. Run "./scripts/feeds install -a" to install symlinks for all obtained
packages into package/feeds/
3. Run "make menuconfig" to select your preferred configuration for the
toolchain, target system & firmware packages.
4. Run "make" to build your firmware. This will download all sources, build
the cross-compile toolchain and then cross-compile the Linux kernel & all
chosen applications for your target system.
