Subject: [PATCH] Makefile: consolidate .FORCE-* targets

Providing multiple targets to force a rebuild is unnecessary
complication.

Avoid using a name that could conflict with future special
targets in GNU make (a leading period followed by uppercase
letters).

The corresponding change to the git-gui Makefile is left for
another patch.
