boot/uboot: use HOSTCC_NOCCACHE as kconfig HOSTCC
At kconfig time, dependencies are not built, and therefore host-ccache is not ready. Due to this, using $(HOSTCC) as the host compiler in KCONFIG_OPTS does not work: a "make uboot-menuconfig" invocation from a clean tree with ccache enabled fails. This commit fixes this by using $(HOSTCC_NOCCACHE). We cannot rely on the default value of HOSTCC passed by the kconfig-package infrastructure, because $(UBOOT_MAKE_OPTS) also contains a HOSTCC definition that would override the one passed by the kconfig-package infrastructure.
