Commit 433290761fceb476b095548eec10adf72405e050 changed the hard-coded
ccache directory location to use BUILDROOT_CACHE_DIR, which is exported
by Makefile based on the BR2_CCACHE_DIR config option.  This allowed the
cache location to be changed on-the-fly by setting an environment
variable, but left the default location of ccache's normal default at
"$HOME/.ccache".  Since this location does not match the default for
BR2_CCACHE_DIR, it is basically almost never correct, so direct invocation
of ccache outside of the buildroot Makefile becomes cumbersome.

This patch changes the last-ditch cache location from "$HOME/.ccache" to
the BR2_CCACHE_DIR value at the time of host-ccache compilation.  Note
that the ability to override the location by BUILDROOT_CACHE_DIR is left
