Makefile.base: Error for C++ code w/w cpp feature

Browse Source 
If external modules use C++ code and forget to require the `cpp` feature,
linking will still take places using $(CC). This commit adds a check if C++ code
was detected without the feature `cpp` being used, now the build is aborted
with a helpful error message rather than a linker error.
