Currently, HOSTCC and HOSTCXX are set to their _NOCACHE variants in the 'dependencies' target. This is needed because at that time, ccache is not built yet - host-ccache is one of the dependencies. However, because this override is only specified for the 'dependencies' target (and thereby gets inherited by its dependencies), the override is only applied when the package is reached through the 'dependencies' target. This is not the case when one of DEPENDENCIES_HOST_PREREQ is built directly from the command line, e.g. when doing 'make host-ccache'. So in that case, ccache will be built with ccache... which fails of course. To fix this, directly apply the override to the DEPENCIES_HOST_PREREQ targets. Note that this only fixes the issue for 'make host-ccache', NOT for e.g. 'make host-ccache-configure'.
