kernel: specify dependencies for compilation for config tasks
With recent kernels (i.e. 4.17+) the configuration phase of the kernel will check for capabilities/options of the compiler for CVE and other mitigation support. For a general kernel, we want to ensure that CC is fully defined when the config targets are invoked (so the proper compiler will be checked). For linux-yocto, we also need to specify the compiler/tools dependencies for the configme task since it executes before configure and hence the main kernel build DEPENDS will not always be in the sysroot before it executes. Without those dependencies the kernel will be incorrectly configured (i.e. bison is missing) or the configuration will fail the mitigation tests.
