Subject: Makefile: add {program,xdiff,test,git,fuzz}-objs & objects targets
X-Git-Tag: v2.32.0-rc0~131^2

Makefile: add {program,xdiff,test,git,fuzz}-objs & objects targets

Add targets to compile the various *.o files we declared in commonly
used *_OBJS variables. This is useful for debugging purposes, to
e.g. get to the point where we can compile a git.o. See [1] for a
use-case for this target.
