This commit separates include/library search directory options from "normal" compiler/linker options and places options passed via the `-COPT`/`-CLNK` command-line flags in-between. This allows overwriting the default search paths, since contrary to all other options, the search paths must be prepend for an -I/-L option to take precedence over an existing one. This should (hopefully) make it entirely unnecessary to ever build Cyclone twice in order to have all changes in the current source tree take effect. Fixes #476
