(svn r1917) - Makefile: Revamped VERBOSE support, build mechanics changed.

- VERBOSE has now greater effect, many previously hidden commands are now shown on the terminal as they are executed. (Use $(Q) instead of @ where the command should be shown if VERBOSE.) - Compilation commands redundancy was eliminated. - Compilation commands calling generalized so that the VERBOSE support does not further entangle the code. The commands are now all at a single place, before the targets in a "Build commands" section. Note that this changeset has a character of proposal. If you do not like the direction it takes at all, feel free to revert it (probably together with the previous VERBOSE patch). However, I believe it improves the code by bringing the compilation commands to a single place and it greatly improves the VERBOSE support, too (and makes it much less intrusive).
