OTP-8373 ERTS makefiles used to detect the use of a gcc C compiler by

          checking if CC equaled gcc. That is, the makefiles failed to
          detect gcc C compilers with other command line names than gcc.
          `configure' now substitute GCC into the makefiles. If CC is a gcc
          C compiler, GCC will have the value yes. (Thanks to
          Jean-S�bastien P�dron)
