[PATCH 3/4] Makefile: fix .s pattern rule dependencies

[Jonathan Nieder <jrnieder@gmail.com>]

'make git.s' fails to regenerate an assembler listing if git.c
has not changed but a header it includes has.  The %.s: %.c
pattern rule is meant to be invoked by hand, so it would be
better to make it always run.

This adds yet another phony .FORCE-foo target.  Wouldn’t it be simpler
to use a single target called .FORCE, or is there something I am
missing that that would break?
