config.vars.in: add CC so a configure CC will be the default

Add CC to config.vars.in (included by GNUMakefile) so that the CC
detected by ./configure will actually become the default.  Previously
it would still reflect GNU make's default, even after something like
this:

  CC=/some/where/gcc ./configure
