Make a possibility to generate Makefile.tcl split in parts

[ethouris]

The goal is to generate various sets of rules independently - separately single objects, also separately for each target, and separately linkage. The goal is that after a trial generation (see #86) every existing file should be checked against the generated ones, and:

• If an existing file has been "removed" (does not exist in the new files), then the clean rule from this file should be executed
• If the file has been changed, then the rules should be loaded and compared. For every rule that is removed or different, the target of that rule should be cleaned.
• If there are new files, then usually the link rule is also altered, so no special things to be done here.

This feature should be turned on in the general profile.
