description:
Restore c++ support in ccache.mk

The ccache.mk file was checking for languages "c" and "c++".
New framework for C++ dialects (or revisions) was setting implicitly c++,
translating e.g. c++11 to c++.

compiler.mk set this c++ after including ccache.mk, so c++ was undefined
and ccache was ignored.

This helps to build large projects like LLVM+Clang+LLDB with ccache.
