You can use git-describe to find the most recent tag. That would allow
the ChangeLog to be generated between the previous two tags. Getting
this two work in a Makefile could be tricky, but here's the gist of it
(git-1.5.0.5):

$ git describe --abbrev=0
HAL_0_5_9
$ CURR_TAG=`git describe --abbrev=0`
$ PREV_TAG=`git describe --abbrev=0 $CURR_TAG^`
$ echo $CURR_TAG $PREV_TAG
HAL_0_5_9 HAL_0_5_8
$ git log --pretty=short $PREV_TAG..$CURR_TAG
