  * milestone:  => MacPorts base bugs

Comment:

 As MacPorts explicitly sets CC and CXX to the full path to the compiler in
 the build environment, extending binpath is not a possible solution for
 using ccache. Also, it will not work with the different compilers we allow
 to select by `configure.compiler`.

 If a port does only accept real paths for CC or CXX or does not understand
 more than one word, add `configure.ccache no` to the port, which will
 disable ccache for it.
