linux is a bit different than other kconfig-package, because it has "toolchain" in KCONFIG_DEPENDENCIES. Thanks to this, host-ccache *is* ready by the time kconfig invocations are made, so we could use $(HOSTCC) as the host compiler for kconfig related operations. However, for consistency with other kconfig-package packages, we chose to use $(HOSTCC_NOCCACHE) as well. We cannot rely on the default value of HOSTCC passed by the kconfig-package infrastructure, because $(LINUX_MAKE_FLAGS) also contains a HOSTCC definition that would override the one passed by the kconfig-package infrastructure.
