 > Currently, HOSTCC and HOSTCXX are set to their _NOCACHE variants in the

 > 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
