build: Support for non-Guix[SD]: make CC/CC32 optional in configure too.

Browse source 
* configure (optional): New global.
  (BUILD_TRIPLET): Use Guile value.
  (check-version): Add keyword argument #:optional.
  (main): Make CC optional (--with-courage).  Only check for stdio.h,
  limits.h if CC is found.
  Make CC32 check optional.
* scripts/scripts.make: Skip if CC is not set.
