jimtcl: don't attempt to handle ccache internally

jimtcl tries to use 'ccache' (a non-buildroot host version) which may not
exist on the host system. If ccache is enabled in buildroot, the compiler
used by jimtcl is:
ccache <buildroot>/.../ccache <buildroot>/.../<tuple>-gcc

If ccache is not present on the host, this results in the build error:

ccache <buildroot>/.../ccache <buildroot>/.../<tuple>-gcc
-D_GNU_SOURCE -Wall  -I. -fpic -pipe -Os    -c -o jim-subcmd.o jim-subcmd.c
make[1]: ccache: Command not found

This patch passes 'CCACHE=none' to the 'configure' script, disabling the
internal handling of ccache, so that ccache can be transparently passed
through CC.

opencv: always enable opencv_core module when opencv is enabled

It does not make much sense enabling opencv without its core module.

This configuration leads to build nothing (since all modules depend on
the core one), but install the configuration files (*.pc and *.cmake)
anyway.

This absurd situation may break the build-system of other packages
that would correctly find the *.pc (but does not check for the modules
they actually use), but would not build because of missing headers and
libraries.
