Merge #1195, #1196 and #1203 from /devel/YEM-build_host_target_cleanup:

- Get rid of CT_CC_NATIVE
- Get rid of CT_CANADIAN_OPT
- Sanitise CT_BUILD vs. CT_HOST

+        installed as gcc-3.4, then you should enter:

-      You can leave this empty as well, in which case gcc will be used.
+      It can happen that some of the tools have a suffix, when others
