Force color diagnostics when applicable

Browse source 
Although GCC and Clang automatically generate color diagnostics on
terminal output, they do not do so when the compiler output is piped
through another process, like in the case for ninja-build and ccache.

Similarly, it would also be nice to be able to see the color diagnostics
on the CI build log in the web interface provided by the CI providers.
