Makefile.inc: Export CCACHE_EXTRAFILES and add __BUILD_DIR__ definition
This patch adds the CCACHE_EXTRAFILES variable to the list of exported
environment variables, which can be useful as a target-specific variable
to make ccache aware of extra dependencies that it cannot figure out on
its own. It also adds a CPPFLAGS parameter to define the __BUILD_DIR__
constant for the preprocessor so that the current output build directory
can be referenced in C code if necessary.
