The problem with this is, that I have to remeber that every time
I issue the command (and my customers as well).
If the first version would work, I could put the variable
in the shell startup file.

I believe that is what I want.
The problem with it is that it works recursively: the definitions
in the main makefile overide the ones from the sub-makefile.
And that causes the sources in the tools directory to be
compiled with the CC from the main makefile, which is the
cross compiler :-(

On each single invocation.  And that is what I want to avoid.
