[ccache] configuring more than one compiler for ccache

[Diane Cronin]

Hi,

I've noticed that when configuring ccache, if gcc is on your path it 
will just pick up and configure ccache for gcc. I need to use the native 
compiler so removing gcc from my path will force it to configure for cc. 
However, during the builds I also use the c++ compiler - how can I get 
the configuration step to also configure this for use? The yields would 
be much improved if the c++ objects were cached also...

Appreciate some pointers,

thanks,
-Diane.
